* Add auth_ad_(group|user)_filter options
* use global
* Fix some AD annoyances
Use the power of the LDAP filter to minimize the number of queries and
hopefully help performance in get_userlist, change semantics of
auth_ad_(user|group)_filter in $config to be anded with
samaccountname=USERNAME.
* remove unused variable
* update documentation
* Update Authentication.md
* Removed duplicate include
* Move set_debug into functions.php, and restore the (re)loading of includes/defaults
* Move debug call until after function has been included
Move the classloader to as early as possible in defaults.inc.php
This should cover all application entrances.
Set install_dir based on the location of defaults.inc.php
* Change the default error_reporting level
This will hopefully save confusion when there are things like syntax errors and missing required files.
* Add E_PARSE error as well.
This is a fatal error too.
A new Discovery/Poller module to collect NTP statistics from devices which support the CISCO-NTP-MIB
Discovered peers are stored using components and statistics are displayed using 'applications'
A critical alarm is raised when a stratum of 16 is reported.
Wait for output on every command, this prevents input left in the buffer from messing up subsequent commands.
It doesn't seem like there is a penalty, but I'd have to do more testing.
- Moved check-services.php to a poller module
- Added performance data collection to the poller
- Centralised DB functions to includes/services.inc.php
- Created add/edit/delete functions off the device, services page
- Removed legacy edit/delete interfaces.
- Moved and modified check.inc scripts
- Documentation Updates
- Modified services table
When using the ifName or ifDescr as means to map discovered ports to
known ports in the DB (think of port association mode) it's possible
that we're facing the problem that the ifName or ifDescr polled from
the device is unset or an empty string (like when querying some ubnt
devices...). If this happends we have no way to map this port to any
port found in the database. As reported this situation may occur for
the time of one poll and might resolve automagically before the next
poller run happens. Without this special case this would lead to new
ports added to the database each time this situation occurs. To give
the user the choice between »a lot of new ports« and »some poll runs
are missed but ports stay stable« the 'ignore_unmapable_port' option
has been added to configure this behaviour. To skip the port in this
loop is sufficient as the next loop is looping only over ports found
in the database and "maps back". As we did not add a new port to the
DB here, there's no port to be mapped to.
I'm using the in_array() check here, as I'm not sure if an "ifIndex"
can be legally set to 0, which would yield True when checking if the
value is empty().

By default libreNMS used the ifIndex to associate ports just found via SNMP
with ports discoverd/polled before and stored in the database. On Linux boxes
this is a problem as ifIndexes are rather likely to be unstable between reboots
or (re)configuration of tunnel interfaces (think: GRE/OpenVPN/Tinc/...), bridges,
Vlan interfaces, Bonding interfaces, etc.
This patch adds a »port association mode« configuration option per device which
allows to map discovered and known ports by their ifIndex, ifName, ifDescr, or
maybe other means in the future.
The default port association mode still is ifIndex for compatibility reasons.
As port RRD files were stored by their ifIndex before, they are now identified
by their unique and stable port_id to ensure a stable and unique mapping and
allow future port association modes to be added without requireing any further
internal changes. Existing RRD files are renamend accordingly in discovery and
poller tools to ensure stability of port associations in both modules as we
don't know which might run first after an update.

This Authentitation / Authorization module provides the ability to let
the webserver (e.g. Apache) do the user Authentication (using Kerberos
f.e.) and let libreNMS do the Authorization of the already known user.
Authorization and setting of libreNMS user level is done by LDAP group
names specified in the configuration file. The group configuration is
basicly copied from the existing ldap Authentication module.
To save lots of redundant queries to the LDAP server and speed up the
libreNMS WebUI, all information is cached within the PHP $_SESSION as
long as specified in $config['auth_ldap_cache_ttl'] (Default: 300s).

Implements the CISCO-OTV-MIB to retrieve OTV counters from Cisco devices.
This collects information on the configured Overlays and Adjacencies
Statistics are collected for the amount of VLAN's on each overlay and the amount of MAC addresses available over each OTV endpoint.
OTV alerts are collected and generated if the appropriate alerting rules exist.
Data is displayed under routing at both the global and device level.
Includes function snmpwalk_array_num, which performs a numeric SNMPWalk and returns an array containing $count indexes
One Index:
From: 1.3.6.1.4.1.9.9.166.1.15.1.1.27.18.655360 = 0
To: $array['1.3.6.1.4.1.9.9.166.1.15.1.1.27.18']['655360'] = 0
Two Indexes:
From: 1.3.6.1.4.1.9.9.166.1.15.1.1.27.18.655360 = 0
To: $array['1.3.6.1.4.1.9.9.166.1.15.1.1.27']['18']['655360'] = 0
And so on...
Implements the CISCO-CLASS-BASED-QOS-MIB to retrieve QOS counters from Cisco devices.
Policy and Class-map details are collected and stored in the database.
Details are presented on a new "CBQoS" tab of the interface that the policy is applied to.
Includes a policy selector that allows you to select which policy-map to show graphs for.
Each class-map has its own rrd file, in which 3 metrics are stored: Bytes, QoS Drops, Buffer Drops.
This can produce a LOT of rrd files.
As an example:
A Cisco 4500 series switch, running MQC on 200 ports. Each port has a common 5 class queueing policy applied, this creates 1000 (5 x 200) RRD's.
Because of this I have currently set:
```
$config['discovery_modules']['cisco-cbqos'] = 0;
```
