check_cisco_ipsla

Project Notes

This check will probe for Cisco IP SLAs.
(Tested on IOS 12.4T release)

For now it only accepts the "-i ALL" argument and it will list and check for all IP SLAs configured on the router.

Return code will be 0 if all probes have completed successfully.
Return code will be 2 if one probe failed

Additionally, performance data is retrieved, as the total time it took to run all IP SLAs. The multi-line output will display the run time of each IP SLA.

On the router side of it, IP SLAs must be configured with a TAG, as follows:

ip sla 1
dns www.google.com name-server 8.8.8.8
tag DNS_Google
frequency 300

ip sla 2
http get http://www.google.com/ name-server 8.8.8.8 cache disable
tag HTTP_Google
frequency 300

ip sla group schedule 1 1-2 schedule-period 300 frequency 300 start-time now life forever

Sample output:
$./check_cisco_ipsla.pl -c public-H 10.10.10.10 -i ALL
IP SLA status: OK | Total-Time=120
IP SLA 1 # DNS_Google ( dns ) status: OK
IP SLA 2 # HTTP_Google ( http ) status: OK | DNS_Google=17
HTTP_Google=93

There's a lot more to do with IP SLAs; feel free to update this script, based on an old "check_snmp_if" or something close to that.

Enjoy it ;-))
