Pingmon Script Modification Help

Hello Community,

The attached script was created by someone from this community.

I was wondering if someone could take a look at it and let me know if it can be modified to allow multiple ping destinations? Also, can it be modified so as to send a syslog message or and email when the ping isn't successful?

Cheers

Carlton

Re: Pingmon Script Modification Help

This should do it.  Just list your destinations separated by space in the pingmon_dstip environment variable.

Re: Pingmon Script Modification Help

So Joseph,

If I want to add multiple ip addresses would I do the following:

event manager environment pingmon_dstip 10.10.13.1 150.50.5.1 170.70.7.1

Also is it possible to just get  syslog message stating pings failed? Or email?

Cheers

Re: Pingmon Script Modification Help

Joseph,

I was being a numbty. I didn't fully read what you said - I can add multiple addresses

However, is there a way to email when ping fails?

Hi Joseph,

I played around with interval in the environment variables and now I'm getting the following error:

event manager environment pingmon_interval 10

event manager directory user policy flash:/

event manager policy pingmon.tcl type user

Appreciate your help

Joesph

Thanks for the update

I just want to get your opinion on what my intentions are with the script.

I'm intend on adding over 50 ip addresses to the variable, is that good practice? Can you think of a more efficient way to add such large number of ip addresses?

Cheers mate

Re: Pingmon Script Modification Help

You could get this script to ping 50 addresses.  What you'd need to at the very least, though, is adjust the maxrun timer to take into account your ping timers.  For example, with the timers above you should set your maxrun to 800.
