* refactor: Centralize MIB include directory specification
The default is now:
```
$config['mib_dir'].'/mibdirname:'.$config['mib_dir']
```
This means we exclude OS mibs and only use ours (we could prepend `+` if we want to include os mibs.
All snmp calls should only include the name of the subdirectory under the mibs directory.
* Remove d_echo from Proc
Fix snmpsim tests.
fallback feature so we don't have to run snmpsim on devel computers, should be adequate for now
./scripts/pre-commit.php -u -snmpsim will start an snmpsimd.py process automatically
* webui: make d_echo work in webui
Remove d_print_r(), it is redundant to d_echo()
Remove d_echo calls in services.inc.php
* Switched debug check to work with nginx
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;
```
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...
Should only replace first occurrence of prefix in the string.
Also only strips the prefix if it saves more than 2 characters.
This fixes a bug where, e.g., 'casnDisconnect' would be shortened to 'asnDisonnet'.
