Remote ping

[parm UK]

Hi guys, 

After some advice please. 

I need to monitor some devices that sit behind certain routers / l3 switches. 

Ideally I want to issue a remote ping fom the router and get an alert if ping fails.   Currently we use prtg for snmp monitoring and I can't work out how to do this. 

Can I use cisco prime infrastructure to do this?   I've dloads the trial,  just need  to know  how I can issue the remote ping and poll the results.   Alternatively if I can monitor / alert on the status of a track reachability that would be ideal. 

I can see manageengine offer a 'proxy ping' out the box

Any suggestions greatly appreciated.

Hi Parm,

actually the PRTG allows to send an e-mail if the SNMP polling fails (depending on the configured timeout).

Either way, if you wanted to try through a PING test, I think the easiest way to get an alert if the ping will fails could be a little script like that:

Of course it's possible to use differents methods, also PHP would be fine, it's easy to manage even for the beginners indeed .

Then you can trigger a whatever alert like an email or sms (through sms gateway etc..) depending on your needs.

I suggest to try the "scripting" way, as it easy, quick and very handy in case you would like to set up a cost '0' solution to monitor a very critical service.

Hope this helps,
Ciao

+1, I would be using PRTG.  If you really want you can configure IP SLA to make one router ping another router/switch, and then have PRTG monitor the IP sla results.

That's exactly what I would like to do. 

For instance I have a 3750 which is already monitored in prtg. 

I have the following ip sla 

Config:

IP sla 100
icmp-echo x.x.x.x
threshold 10
timeout 1000
frequency 3

ip sla schedule 100 start-time now life forever

track 100 ip sla 100 reachability

I need some help in how I get prtg to monitor this ip  sla / track result. 

You help appreciated 

Thanks

Just add the "ip sla" sensor ...
