The options shown below also contain the default values.
|
|
|
|
If you would like to alter any of these then please add your config option to `config.php`.
|
|
|
|
# Directories
|
|
|
|
```php
|
|
$config['install_dir'] = "/opt/librenms";
|
|
```
|
|
|
|
Set the installation directory (defaults to /opt/librenms), if you
|
|
clone the GitHub branch to another location ensure you alter this.
|
|
|
|
```php
|
|
$config['temp_dir'] = "/tmp";
|
|
```
|
|
|
|
The temporary directory is where images and other temporary files are
|
|
created on your filesystem.
|
|
|
|
```php
|
|
$config['log_dir'] = "/opt/librenms/logs";
|
|
```
|
|
|
|
Log files created by LibreNMS will be stored within this directory.
|
|
|
|
# Database config
|
|
|
|
Set these variables either in .env or in the environment.
|
|
|
|
```dotenv
|
|
DB_HOST=127.0.0.1
|
|
DB_DATABASE=librenms
|
|
DB_USERNAME=DBUSER
|
|
DB_PASSWORD="DBPASS"
|
|
```
|
|
|
|
Use non-standard port:
|
|
|
|
```dotenv
|
|
DB_PORT=3306
|
|
```
|
|
|
|
Use a unix socket:
|
|
|
|
```dotenv
|
|
DB_SOCKET=/run/mysqld/mysqld.sock
|
|
```
|
|
|
|
# Core
|
|
|
|
## PHP Settings
|
|
|
|
You can change the memory limits for php within `config.php`. The
|
|
value is in Megabytes and should just be an int value:
|
|
|
|
`$config['php_memory_limit'] = 128;`
|
|
|
|
## Programs
|
|
|
|
A lot of these are self explanatory so no further information may be
|
|
provided. Any extensions that have dedicated documentation page will
|
|
be linked to rather than having the config provided.
|
|
|
|
### RRDTool
|
|
|
|
> You can configure these options within the WebUI now, please avoid
|
|
> setting these options within config.php
|
|
>
|
|
> Settings -> External Settings -> RRDTool Setup
|
|
|
|
```php
|
|
$config['rrdtool'] = "/usr/bin/rrdtool";
|
|
```
|
|
|
|
Please see [1 Minute polling](1-Minute-Polling.md) for information on
|
|
configuring your install to record data more frequently.
|
|
|
|
### fping
|
|
|
|
```php
|
|
$config['fping'] = "/usr/bin/fping";
|
|
$config['fping6'] = "fping6";
|
|
$config['fping_options']['timeout'] = 500;
|
|
$config['fping_options']['count'] = 3;
|
|
$config['fping_options']['interval'] = 500;
|
|
```
|
|
|
|
`fping` configuration options:
|
|
|
|
* `timeout` (`fping` parameter `-t`): Amount of time that fping waits
|
|
for a response to its first request (in milliseconds). **See note
|
|
below**
|
|
* `count` (`fping` parameter `-c`): Number of request packets to send
|
|
to each target.
|
|
* `interval` (`fping` parameter `-p`): Time in milliseconds that fping
|
|
waits between successive packets to an individual target.
|
|
|
|
> NOTE: Setting a higher timeout value than the interval value can
|
|
> lead to slowing down poller. Example:
|
|
>
|
|
> timeout: 3000
|
|
>
|
|
> count: 3
|
|
>
|
|
> interval: 500
|
|
>
|
|
> In this example, interval will be overwritten by the timeout value
|
|
> of 3000 which is 3 seconds. As we send three icmp packets (count:
|
|
> 3), each one is delayed by 3 seconds which will result in fping
|
|
> taking > 6 seconds to return results.
|
|
|
|
You can disable the fping / icmp check that is done for a device to be
|
|
determined to be up on a global or per device basis. **We don't advise
|
|
disabling the fping / icmp check unless you know the impact, at worst
|
|
if you have a large number of devices down then it's possible that the
|
|
poller would no longer complete in 5 minutes due to waiting for snmp
|
|
to timeout.**
|
|
|
|
Globally disable fping / icmp check:
|
|
|
|
```php
|
|
$config['icmp_check'] = false;
|
|
```
|
|
|
|
If you would like to do this on a per device basis then you can do so
|
|
under Device -> Edit -> Misc -> Disable ICMP Test? On
|
|
|
|
### traceroute
|
|
|
|
LibreNMS uses traceroute / traceroute6 to record debug information
|
|
when a device is down due to icmp AND you have
|
|
`$config['debug']['run_trace'] = true;` set.
|
|
|
|
```php
|
|
$config['traceroute'] = '/usr/bin/traceroute';
|
|
$config['traceroute6'] = '/usr/bin/traceroute6';
|
|
```
|
|
|
|
### SNMP
|
|
|
|
```php
|
|
$config['snmpwalk'] = "/usr/bin/snmpwalk";
|
|
$config['snmpget'] = "/usr/bin/snmpget";
|
|
$config['snmpbulkwalk'] = "/usr/bin/snmpbulkwalk";
|
|
```
|
|
|
|
SNMP program locations.
|
|
|
|
```php
|
|
$config['whois'] = "/usr/bin/whois";
|
|
$config['ping'] = "/bin/ping";
|
|
$config['mtr'] = "/usr/bin/mtr";
|
|
$config['nmap'] = "/usr/bin/nmap";
|
|
$config['nagios_plugins'] = "/usr/lib/nagios/plugins";
|
|
$config['ipmitool'] = "/usr/bin/ipmitool";
|
|
$config['virsh'] = "/usr/bin/virsh";
|
|
$config['dot'] = "/usr/bin/dot";
|
|
$config['unflatten'] = "/usr/bin/unflatten";
|
|
$config['neato'] = "/usr/bin/neato";
|
|
$config['sfdp'] = "/usr/bin/sfdp";
|
|
```
|
|
|
|
# Authentication
|
|
|
|
Generic Authentication settings.
|
|
|
|
```php
|
|
$config['password']['min_length'] = 8; // password minimum length for auth that allows user creation
|
|
```
|
|
|
|
# Proxy support
|
|
|
|
For alerting and the callback functionality, we support the use of a
|
|
http proxy setting. These can be any one of the following:
|
|
|
|
```php
|
|
$config['callback_proxy'] = 'proxy.domain.com';
|
|
$config['http_proxy'] = 'proxy.domain.com';
|
|
```
|
|
|
|
We can also make use of one of these environment variables which can be set in `/etc/environment`:
|
|
|
|
```bash
|
|
http_proxy=proxy.domain.com
|
|
https_proxy=proxy.domain.com
|
|
```
|

|
|
# WebUI Settings
|
|
|
|
```php
|
|
$config['base_url'] = "http://demo.librenms.org";
|
|
```
|
|
|
|
LibreNMS will attempt to detect the URL you are using but you can override that here.
|
|
|
|
```php
|
|
$config['site_style'] = "light";
|
|
```
|
|
|
|
Currently we have a number of styles which can be set which will alter
|
|
the navigation bar look. dark, light and mono with light being the default.
|
|
|
|
```php
|
|
$config['webui']['custom_css'][] = "css/custom/styles.css";
|
|
```
|
|
|
|
You can override a large number of visual elements by creating your
|
|
own css stylesheet and referencing it here, place any custom css files
|
|
into `html/css/custom` so they will be ignored by auto updates. You
|
|
can specify as many css files as you like, the order they are within
|
|
your config will be the order they are loaded in the browser.
|
|
|
|
```php
|
|
$config['title_image'] = "images/custom/yourlogo.png";
|
|
```
|
|
|
|
You can override the default logo with yours, place any custom images
|
|
files into `html/images/custom` so they will be ignored by auto updates.
|
|
|
|
```php
|
|
$config['page_refresh'] = "300";
|
|
```
|
|
|
|
Set how often pages are refreshed in seconds. The default is every 5
|
|
minutes. Some pages don't refresh at all by design.
|
|
|
|
```php
|
|
$config['front_page'] = "default";
|
|
```
|
|
|
|
You can create your own front page by adding a blade file in `resources/views/overview/custom/`
|
|
and setting `front_page` to it's name.
|
|
For example, if you create `resources/views/overview/custom/foobar.blade.php`, set `front_page` to `foobar`.
|
|
|
|
```php
|
|
// This option exists in the web UI, edit it under Global Settings -> webui
|
|
$config['webui']['default_dashboard_id'] = 0;
|
|
```
|
|
|
|
Allows the specification of a global default dashboard page for any user who
|
|
has not set one in their user preferences. Should be set to dashboard_id of an
|
|
existing dashboard that is shared or shared(read). Otherwise, the system will
|
|
automatically create each user an empty dashboard called `Default` on their
|
|
first login.
|
|
|
|
```php
|
|
$config['login_message'] = "Unauthorised access or use shall render the user liable to criminal and/or civil prosecution.";
|
|
```
|
|
|
|
This is the default message on the login page displayed to users.
|
|
|
|
```php
|
|
$config['public_status'] = false;
|
|
```
|
|
|
|
If this is set to true then an overview will be shown on the login page of devices and the status.
|
|
|
|
```php
|
|
$config['show_locations'] = 1; # Enable Locations on menu
|
|
$config['show_locations_dropdown'] = 1; # Enable Locations dropdown on menu
|
|
$config['show_services'] = 0; # Enable Services on menu
|
|
$config['int_customers'] = 1; # Enable Customer Port Parsing
|
|
$config['summary_errors'] = 0; # Show Errored ports in summary boxes on the dashboard
|
|
$config['customers_descr'] = 'cust'; // The description to look for in ifDescr. Can be an array as well array('cust','cid');
|
|
$config['transit_descr'] = 'transit'; // Add custom transit descriptions (can be an array)
|
|
$config['peering_descr'] = 'peering'; // Add custom peering descriptions (can be an array)
|
|
$config['core_descr'] = 'core'; // Add custom core descriptions (can be an array)
|
|
$config['custom_descr'] = ''; // Add custom interface descriptions (can be an array)
|
|
$config['int_transit'] = 1; # Enable Transit Types
|
|
$config['int_peering'] = 1; # Enable Peering Types
|
|
$config['int_core'] = 1; # Enable Core Port Types
|
|
$config['int_l2tp'] = 0; # Enable L2TP Port Types
|
|
```
|
|
|
|
Enable / disable certain menus from being shown in the WebUI.
|
|
|
|
You are able to adjust the number and time frames of the quick select
|
|
time options for graphs and the mini graphs shown per row.
|
|
|
|
Quick select:
|
|
|
|
```php
|
|
$config['graphs']['mini']['normal'] = array(
|
|
'day' => '24 Hours',
|
|
'week' => 'One Week',
|
|
'month' => 'One Month',
|
|
'year' => 'One Year',
|
|
);
|
|
$config['graphs']['mini']['widescreen'] = array(
|
|
'sixhour' => '6 Hours',
|
|
'day' => '24 Hours',
|
|
'twoday' => '48 Hours',
|
|
'week' => 'One Week',
|
|
'twoweek' => 'Two Weeks',
|
|
'month' => 'One Month',
|
|
'twomonth' => 'Two Months',
|
|
'year' => 'One Year',
|
|
'twoyear' => 'Two Years',
|
|
);
|
|
```
|
|
|
|
Mini graphs:
|
|
|
|
```php
|
|
$config['graphs']['row']['normal'] = array(
|
|
'sixhour' => '6 Hours',
|
|
'day' => '24 Hours',
|
|
'twoday' => '48 Hours',
|
|
'week' => 'One Week',
|
|
'twoweek' => 'Two Weeks',
|
|
'month' => 'One Month',
|
|
'twomonth' => 'Two Months',
|
|
'year' => 'One Year',
|
|
'twoyear' => 'Two Years',
|
|
);
|
|
```
|
|
|
|
```php
|
|
$config['web_mouseover'] = true;
|
|
```
|
|
|
|
You can disable the mouseover popover for mini graphs by setting this to false.
|
|
|
|
```php
|
|
$config['enable_lazy_load'] = true;
|
|
```
|
|
|
|
You can disable image lazy loading by setting this to false.
|
|
|
|
```php
|
|
$config['show_overview_tab'] = true;
|
|
```
|
|
|
|
Enable or disable the overview tab for a device.
|
|
|
|
```php
|
|
$config['overview_show_sysDescr'] = true;
|
|
```
|
|
|
|
Enable or disable the sysDescr output for a device.
|
|
|
|
```php
|
|
$config['force_ip_to_sysname'] = false;
|
|
```
|
|
|
|
When using IP addresses as a hostname you can instead represent the
|
|
devices on the WebUI by its SNMP sysName resulting in an easier to
|
|
read overview of your network. This would apply on networks where you
|
|
don't have DNS records for most of your devices.
|
|
|
|
```php
|
|
$config['force_hostname_to_sysname'] = false;
|
|
```
|
|
|
|
When using a dynamic DNS hostname or one that does not resolve, this
|
|
option would allow you to make use of the SNMP sysName instead as the
|
|
preferred reference to the device.
|
|
|
|
```php
|
|
$config['device_traffic_iftype'][] = '/loopback/';
|
|
```
|
|
|
|
Interface types that aren't graphed in the WebUI. The default array
|
|
contains more items, please see misc/config_definitions.json for the full list.
|
|
|
|
```php
|
|
$config['enable_clear_discovery'] = 1;
|
|
```
|
|
|
|
Administrators are able to clear the last discovered time of a device
|
|
which will force a full discovery run within the configured 5 minute cron window.
|
|
|
|
```php
|
|
$config['enable_footer'] = 1;
|
|
```
|
|
|
|
Disable the footer of the WebUI by setting `enable_footer` to 0.
|
|
|
|
You can enable the old style network map (only available for
|
|
individual devices with links discovered via xDP) by setting:
|
|
|
|
```php
|
|
$config['gui']['network-map']['style'] = 'old';
|
|
```
|
|
|
|
```php
|
|
$config['percentile_value'] = X;
|
|
```
|
|
|
|
Show the `X`th percentile in the graph instead of the default 95th percentile.
|
|
|
|
```php
|
|
$config['shorthost_target_length'] = X;
|
|
```
|
|
|
|
The target maximum hostname length when applying the shorthost() function.
|
|
You can increase this if you want to try and fit more of the hostname in graph titles.
|
|
The default value is 12 However, this can possibly break graph
|
|
generation if this is very long.
|
|
|
|
You can enable dynamic graphs within the WebUI under Global Settings
|
|
-> Webui Settings -> Graph Settings.
|
|
|
|
Graphs will be movable/scalable without reloading the page:
|
|
|
|
|
|
## Stacked Graphs
|
|
|
|
You can enable stacked graphs instead of the default inverted
|
|
graphs. Enabling them is possible via webui Global Settings -> Webui
|
|
Settings -> Graph settings -> Use stacked graphs
|
|
|
|
## Add host settings
|
|
|
|
The following setting controls how hosts are added. If a host is
|
|
added as an ip address it is checked to ensure the ip is not already
|
|
present. If the ip is present the host is not added. If host is added
|
|
by hostname this check is not performed. If the setting is true
|
|
hostnames are resolved and the check is also performed. This helps
|
|
prevents accidental duplicate hosts.
|
|
|
|
```php
|
|
$config['addhost_alwayscheckip'] = false; #true - check for duplicate ips even when adding host by name.
|
|
#false- only check when adding host by ip.
|
|
```
|
|
|
|
By default we allow hosts to be added with duplicate sysName's, you
|
|
can disable this with the following config:
|
|
|
|
```php
|
|
$config['allow_duplicate_sysName'] = false;
|
|
```
|
|
|
|
# Global poller and discovery modules
|
|
|
|
Generally, it is a better to set these [per
|
|
OS](../Developing/os/Settings.md#poller-and-discovery-modules) or
|
|
device.
|
|
|
|
```php
|
|
$config['discovery_modules]['arp-table'] = true;
|
|
$config['poller_modules']['bgp-peers'] = false;
|
|
```
|
|
|
|
# SNMP Settings
|
|
|
|
Default SNMP options including retry and timeout settings and also
|
|
default version and port.
|
|
|

$config['snmp']['timeout'] = 1; # timeout in seconds
|
|
$config['snmp']['retries'] = 5; # how many times to retry the query
|
|

with `[1]`, `[2]`, `[3]`, etc.
|
|
|
|
```php
|
|
$config['snmp']['community'][0] = "public";
|
|
```
|
|
>NOTE: This list of SNMP communities is used for auto discovery, and as a default set for any manually added device.
|
|
|
|
The default v3 snmp details to use, you can expand this array with
|
|
`[1]`, `[2]`, `[3]`, etc.
|
|
|
|
```php
|

## CollectD
|
|
|
|
```php
|
|
$config['collectd_dir'] = '/var/lib/collectd/rrd';
|
|
```
|
|
|
|
Specify the location of the collectd rrd files. Note that the location
|
|
in config.php should be consistent with the location set in
|
|
/etc/collectd.conf and etc/collectd.d/rrdtool.conf
|
|
|
|
```php
|
|
<Plugin rrdtool>
|
|
DataDir "/var/lib/collectd/rrd"
|
|
CreateFilesAsync false
|
|
CacheTimeout 120
|
|
CacheFlush 900

```php
|
|
$config['collectd_sock'] = 'unix:///var/run/collectd.sock';
|
|
```
|
|
|
|
Specify the location of the collectd unix socket. Using a socket
|
|
allows the collectd graphs to be flushed to disk before being
|
|
drawn. Be sure that your web server has permissions to write to this socket.

## Location mapping
|
|
|
|
If you just want to set GPS coordinates on a location, you should
|
|
visit Devices > Geo Locations > All Locations and edit the coordinates
|
|
there.
|
|
|
|
Exact Matching:
|
|
|
|
```php
|
|
$config['location_map']['Under the Sink'] = "Under The Sink, The Office, London, UK";
|
|
```
|
|
|
|
Regex Matching:
|
|
|
|
```php
|
|
$config['location_map_regex']['/Sink/'] = "Under The Sink, The Office, London, UK";
|
|
```
|
|
|
|
Regex Match Substitution:
|
|
|
|
```php
|
|
$config['location_map_regex_sub']['/Sink/'] = "Under The Sink, The Office, London, UK [lat, long]";
|
|
```
|
|
|
|
If you have an SNMP SysLocation of "Rack10,Rm-314,Sink", Regex Match
|
|
Substition yields "Rack10,Rm-314,Under The Sink, The Office, London,
|
|
UK [lat, long]". This allows you to keep the SysLocation string short
|
|
and keeps Rack/Room/Building information intact after the substitution.
|
|
|
|
The above are examples, these will rewrite device snmp locations so
|
|
you don't need to configure full location within snmp.

# Interfaces to be ignored
|
|
|
|
Interfaces can be automatically ignored during discovery by modifying
|
|
bad_if\* entries in a default array, unsetting a default array and
|
|
customizing it, or creating an OS specific array. The preferred method
|
|
for ignoring interfaces is to use an OS specific array. The default
|
|
arrays can be found in misc/config_definitions.json. OS specific
|
|
definitions (includes/definitions/_specific_os_.yaml) can contain
|
|
bad_if\* arrays, but should only be modified via pull-request as
|
|
manipulation of the definition files will block updating.
|
|
|
|
Examples:
|
|
|
|
**Add entries to default arrays**
|
|
```php
|
|
$config['bad_if'][] = "voip-null";
|
|
$config['bad_iftype'][] = "voiceEncap";
|
|
$config['bad_if_regexp'][] = '/^lo[0-9].*/'; // loopback
|
|
```
|
|
|
|
**Unset and customize a default array**
|
|
```php
|
|
unset($config['bad_if']);
|
|
$config['bad_if'][] = "voip-null";
|
|
$config['bad_if'][] = "voiceEncap";
|
|
$config['bad_if'][] = "voiceFXO";
|
|
...
|
|
```
|
|
|
|
**Create an OS specific array**
|
|
```php
|
|
$config['os']['iosxe']['bad_iftype'][] = "macSecControlledIF";
|
|
$config['os']['iosxe']['bad_iftype'][] = "macSecUncontrolledIF";
|
|
```
|
|
|
|
**Various bad_if\* selection options available**
|
|
|
|
`bad_if` is matched against the ifDescr value.
|
|
|
|
`bad_iftype` is matched against the ifType value.
|
|
|
|
`bad_if_regexp` is matched against the ifDescr value as a regular expression.
|
|
|
|
`bad_ifname_regexp` is matched against the ifName value as a regular expression.
|
|
|
|
`bad_ifalias_regexp` is matched against the ifAlias value as a regular expression.
|
|
|
|
# Interfaces that shouldn't be ignored
|
|
|
|
Examples:
|
|
|
|
```php
|
|
$config['good_if'][] = 'FastEthernet';
|
|
$config['os']['ios']['good_if'][] = 'FastEthernet';
|
|
```
|
|
|
|
`good_if` is matched against ifDescr value. This can be a bad_if value
|
|
as well which would stop that port from being ignored. I.e If bad_if
|
|
and good_if both contained FastEthernet then ports with this value in
|
|
the ifDescr will be valid.
|
|
|
|
# Interfaces to be rewritten
|
|
|
|
```php
|
|
$config['rewrite_if']['cpu'] = 'Management Interface';
|
|
$config['rewrite_if_regexp']['/cpu /'] = 'Management ';
|
|
```
|
|
|
|
Entries defined in `rewrite_if` are being replaced completely.
|
|
Entries defined in `rewrite_if_regexp` only replace the match.
|
|
Matches are compared case-insensitive.

# Entity sensors to be ignored
|
|
|
|
Some devices register bogus sensors as they are returned via SNMP but
|
|
either don't exist or just don't return data. This allows you to
|
|
ignore those based on the descr field in the database. You can either
|
|
ignore globally or on a per os basis.
|
|
|
|
```php
|
|
$config['bad_entity_sensor_regex'][] = '/Physical id [0-9]+/';
|
|
$config['os']['cisco']['bad_entity_sensor_regex'] = '/Physical id [0-9]+/';
|
|
```
|
|
|
|
# Entity sensors limit values
|
|
|
|
Vendors may give some limit values (or thresholds) for the discovered
|
|
sensors. By default, when no such value is given, both high and low
|
|
limit values are guessed, based on the value measured during the initial discovery.
|
|
|
|
When it is preferred to have no high and/or low limit values at all if
|
|
these are not provided by the vendor, the guess method can be disabled:
|
|
|
|
```php
|
|
$config['sensors']['guess_limits'] = false;
|
|
```
|
|
|
|
# Ignoring Health Sensors
|
|
|
|
It is possible to filter some sensors from the configuration:
|
|
|
|
* Ignore all temperature sensors
|
|
|
|
```php
|
|
$config['disabled_sensors']['current'] = true;
|
|
```
|
|
|
|
* Filter all sensors matching regexp ```'/PEM Iout/'```.
|
|
|
|
```php
|
|
$config['disabled_sensors_regex'][] = '/PEM Iout/';
|
|
```
|
|
|
|
* Filter all 'current' sensors for Operating System 'vrp'.
|
|
|
|
```php
|
|
$config['os']['vrp']['disabled_sensors']['current'] = true;
|
|
```
|
|
|
|
* Filter all sensors matching regexp ```'/PEM Iout/'``` for Operating System iosxe.
|
|
|
|
```php
|
|
$config['os']['iosxe']['disabled_sensors_regex'][] = '/PEM Iout/';
|
|
```
|
|
|
|

|
|
```
|
|
|
|
Enable this to switch on support for libvirt along with `libvirt_protocols`
|
|
to indicate how you connect to libvirt. You also need to:
|
|
|
|
1. Generate a non-password-protected ssh key for use by LibreNMS, as the
|
|
user which runs polling & discovery (usually `librenms`).
|
|
1. On each VM host you wish to monitor:
|
|
1. Configure public key authentication from your LibreNMS server/poller by
|
|
adding the librenms public key to `~root/.ssh/authorized_keys`.
|
|
1. (xen+ssh only) Enable libvirtd to gather data from xend by setting
|
|
`(xend-unix-server yes)` in `/etc/xen/xend-config.sxp` and
|
|
restarting xend and libvirtd.
|
|
|
|
To test your setup, run `virsh -c qemu+ssh://vmhost/system list` or
|
|
`virsh -c xen+ssh://vmhost list` as your librenms polling user.
