Cisco IOS-XR RSP and LC CPU monitoring: script and templates

[acivciss]

Script is written in python and tested on python 2.7.3.
Created for Cisco IOS-XR CRS-3 and ASR9010.
Tested on cacti 0.8.7i.
For snmp queries you need snmpwalk and snmpget installed.
By default snmp v2c is used.

- unzip cisco_iosxr_cpu_stats.zip
- copy script_query_get_iosxr_cpu_stats.xml into CACTI_HOME/resource/script_queries/
- copy script_get_iosxr_cpu_stats.py into CACTI_HOME/scripts/
- through cacti web interface import templates: graph_data_template_cisco_iosxr_cpu_stats.xml and data_query_template_cisco_iosxr_cpu_stats.xml

Thanks for posting this, seems like its what we currently need

However Im getting this when I try to create the graph:

This data query returned 0 rows, perhaps there was a problem executing this data query. You can run this data query in debug mode to get more information.

Our debug info

+ Running data query [20].
+ Found type = '4' [Script Query].
+ Found data query XML file at '/usr/share/cacti/resource/script_queries/script_query_get_cisco_iosxr_cpu_stats.xml'

+ Executing script query '/usr/bin/env python /usr/share/cacti/scripts/script_get_cisco_iosxr_cpu_stats.py XXX.XXX.XXX.XXX community query query'

What could be the problem here?

Please check if the script is working correctly from the cli. Just run it from cli using correct IP address and community:

/usr/bin/env python /usr/share/cacti/scripts/script_get_cisco_iosxr_cpu_stats.py XXX.XXX.XXX.XXX community num_indexes
/usr/bin/env python /usr/share/cacti/scripts/script_get_cisco_iosxr_cpu_stats.py XXX.XXX.XXX.XXX community index

The output should be something like that, depends on how many cpus you have:

/usr/bin/env python /usr/share/cacti/scripts/script_get_cisco_iosxr_cpu_stats.py 192.168.111.111 public num_indexes
6
/usr/bin/env python /usr/share/cacti/scripts/script_get_cisco_iosxr_cpu_stats.py 192.168.111.111 public index
66
82
2050
16777282
16777298
16779266

If you will have problems with the output from the script, you need to check that snmpwalk and snmpget utilities are correctly installed and the script can find them using system path.
Run that command using your router IP and community:

snmpwalk -v2c -c public 192.168.111.111 .1.3.6.1.4.1.9.9.109.1.1.1.1.2

iso.3.6.1.4.1.9.9.109.1.1.1.1.2.66 = INTEGER: 38557239
iso.3.6.1.4.1.9.9.109.1.1.1.1.2.82 = INTEGER: 56744940
iso.3.6.1.4.1.9.9.109.1.1.1.1.2.2050 = INTEGER: 16203662
iso.3.6.1.4.1.9.9.109.1.1.1.1.2.16777282 = INTEGER: 168504586
iso.3.6.1.4.1.9.9.109.1.1.1.1.2.16777298 = INTEGER: 159516845
iso.3.6.1.4.1.9.9.109.1.1.1.1.2.16779266 = INTEGER: 176960415

If it is not in the system path the simple solution is to copy snmpget and snmpwalk to the directory where the script is located.

Thanks for your reply

I get these errors when invoking the script via CLI

Our server runs CentOS 6, which includes python ver 2.6.6 - would the lower version be the issue here?

[acivciss]

Yes, the problem is with the python version.
Please replace your script_get_cisco_iosxr_cpu_stats.py with the new one. I've changed it to support python < 2.7.
I hope this time it will work.

[havok1977]

Yeah, the Python version was the issue; in case anyone has the same OS this is how you install the newer version in parallel to avoid clashes:

Heh, we worked on it at the same time I'll test this version and let you know how it goes

Works perfectly, thanks again!

You're welcome!

Hope graphs are OK too.
