Snmp vrrp check
Script : check_snmp_vrrp.pl Last update : Sept 4 2006

Description :

Checks by snmp v1, v2c or v3 the vrrp status of all vrrp enabled interfaces.
Works on
- Nokia IP with ipso 3.X , 4.X in VRRP mode.
- Nokia IP with ipso 3.X , 4.X in clustering mode.
- Radware Linkproof
- Alteon AD4 Loadbalancers

Depending on the state you put as option ("master" or "backup") the script will get all the vrrp enables interface and check they are in this state.
If not, it will retrun a critical status
By default, it will check Nokia IP platforms using vrrp, you can test other platforms with the '-T' option :
- Alteon
- Linkproof (VRRP)
- Nokia clustering.

Nokia clustering check

Nokia clustering check does not have a master & backup state. Instead, the plugin will check :

- The number of cluster member
- The % load on each cluster.

For example -s 2,90 will issue
- A critical level if there is not 2 members.
- A warning level if more than 90% is assigned to one cluster member.

To have a long output, put the '-g' option.

French : Vérifie par snmp v1 ou v3 l'état des interfaces vrrp : Nokia, Linkproof, Altéon ou l'état d'un cluster Nokia.

Requirements :

- Perl in /usr/bin/perl - or just run 'perl script'
- Net::SNMP
- file 'utils.pm' in plugin diretory

Dowload lastest version : 1.3

Configurations examples

Examples :

All examples below are considering the script is local directory. Host to be checked is 127.0.0.1 with snmp community "public".

If multiple interfaces are selected, all must be up to get an OK result

Get help | ./check_snmp_vrrp.pl -h
snmpv3 login | ./check_snmp_vrrp.pl -H 127.0.0.1 -l login -x passwd
Check vrrp state of a node to be master. | ./check_snmp_vrrp.pl -H 127.0.0.1 -C public -s master
Output example : The ouput is : <vrid>(<state>,<status>,<priority>) | Vrid : 10(master/up/100), 1(master/up/100), 3(master/up/100), 2(master/up/100), : All master :OK
Check vrrp state of a node to be backup. | ./check_snmp_vrrp.pl -H 127.0.0.1 -C public -s backup
Output example : | Vrid : 1(backup/up/95), 3(backup/up/95), 10(backup/up/95), 2(backup/up/95), : All backup :OK
Test a Linkproof | ./check_snmp_vrrp.pl -H 127.0.0.1 -C public -s master -T lp
Test a Nokia cluster : 2 cluster members and max 90% load assigned to one cluster. | ./check_snmp_vrrp.pl -H 127.0.0.1 -C public -s 2,90%-T ipso
