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.

| snmpv3 login |

Check vrrp state of a node to be 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

cluster. |
