Cisco ISR 4300 (CPU & Mem) Graph templates

[Pucho]

Hi there,

Based on http://forums.cacti.net/viewtopic.php?f=12&t=54205

I created these templates. I've only tested these templates on Cisco ISR 4331 and 4321.

If you are insterested on what the OIDs are, check the data templates.

[update]I've just realised about the ugly ds names so I changed them to make them shorter[/update]

Cheers,

Good stuff. FYI works great on a 4351 running 16.3.3 (Denali) software too. I'm going to see if I can make one for temperature.

Here's mine for Temperature. FYI this should work on all 4000 series and the ISR 1000 series as well.

Nice job! I'm going to test it now

I had a little problem with temp template. I mean, it is a different snmp oid between ISR4331 and ISR4321:
ISR4331
[root@cacti ~]# snmpwalk -c pass -v 2c 10.110.255.1 1.3.6.1.2.1.47 |grep Temp
SNMPv2-SMI::mib-2.47.1.1.1.1.2.7001 = STRING: "Temp: Inlet"

I used your template but I modified it for specific type of router.

Now I`m looking for the same but CPU. When I use your template, the cpu usage is about 15% but real CPU usage is 0%. The snmp oid is for older types of routers I mean. Is it possible that value 15% is zero and I have to decrement the value with 15? Because if I make a higher CPU usage, graph is higher too.
Can you help me? Thank you very much for your work and sorry for my english.

Yep, Cisco used to be pretty good at this, in the past, now days is becoming a real crap and I've been working with cisco techs for long time now..

I'm working on a new snmp data query to be able to walk through the existing sensors for IOS-XE and IOS-XR. Hardcoding OIDs was never a good practice anyway.

EDIT: Just in case you want to work around it, these are the OIDs for single CPUs

busyPer - 1.3.6.1.4.1.9.2.1.56 = CPU busy percentage in the last 5 second period. Not the last 5 realtime seconds but the last 5 second period in the scheduler.
avgBusy1 - 1.3.6.1.4.1.9.2.1.57 = 1 minute exponentially-decayed moving average of the CPU busy percentage.
avgBusy5 - 1.3.6.1.4.1.9.2.1.58 = 5 minute exponentially-decayed moving average of the CPU busy percentage.

I recently got educated a bit on platform vs. processor CPU and Memory on IOS-XE. You can get vastly different results between the two:

Code: Select all

ISR4351#sh proc cpu
CPU utilization for five seconds: 1%/0%; one minute: 1%; five minutes: 1%

ISR4351#sh proc cpu platform 
CPU utilization for five seconds: 11%, one minute: 12%, five minutes: 11%

ISR4351#sh proc mem
Processor Pool Total: 1839882264 Used:  287575728 Free: 1552306536
 lsmpi_io Pool Total:    6295128 Used:    6294296 Free:        832

ISR4351#show platform resources 
**State Acronym: H - Healthy, W - Warning, C - Critical                                             
Resource                 Usage                 Max             Warning         Critical        State
----------------------------------------------------------------------------------------------------
RP0 (ok, active)                                                                               H    
 Control Processor       2.90%                 100%            90%             95%             H    
  DRAM                   3303MB(87%)           3790MB          90%             95%             H  

So I've done a rewrite and can see this in action. Have tested this on an ISR 4351 and ASR 1001x, but it should work for anything IOS-XE...

As far as Temperature it looks like anything will have to be model-specific.

Johnny Lingo - Nice template for CPU and Memory. Are you able to share these please?

Thanks in Advance

Hey there, sorry I dropped off. My company was acquired a few days after posting, so I lost track of this project for a bit.

I had to downgrade from 1.1 to 0.8.8.f, so whipped up a new template that I could fully test. For now it's a simplified version that only does 1 minute CPU checks, but may add the 5sec and 5min ones back in fairly soon.

Thank you to everyone who contributed here. I am so glad i found this thread. Awesome stuff guys.
