How to set alerts when the values goes below the range

[prashanthm88]

I want to send notifications when the values goes below the assigned range.

Example:

No of VPN connections connected to a router is "3". I want to send notification if the values changes to "2" , "1" or "0".

Thank You.

What check/command are you currently using to assess the VPN connections?

[prashanthm88]

check_snmp

I meant the whole command, arguments included. There is a way to define a threshold for some plugins, check_snmp included:

THis is the command I'm looking for.

check_stuff -w10: -c20 Critical if "stuff" is over 20, else warn if "stuff" is below 10 (will be critical if "stuff" is less than 0)

Thank you very much.

Do you have the check_snmp command working with the ranges you need, or are you asking us to give a working example?

Thanks you very much for the quick reply.

I have checked with the command

check_snmp -o XXXXXXXXX -U snmpuser -A password -x AES -X testpassword -L authPriv -P 3 -a MD5 -w3:

Result : SNMP OK - 3 | iso.3.6.1.4.1.9.9.392.1.3.29.0=3


Changed the value to -w4:

Result: SNMP WARNING - *3* | iso.3.6.1.4.1.9.9.392.1.3.29.0=3

Email notification's are also working fine without any issues.

Thank you.
