[c-nsp] Script to track memory leaks?

[Ziv Leyes]

Do you have this feature available in your router ?

If not, you could run a script from a linux box with a remote ssh command and cut the output to your needs, and then feed it into a rrd file or whatever.
But given the fact the command "sh proc mem" gives you a lot of colums/lines and they change all the time, you need to narrow down and pin a specific value you want to graph.

If you have ssh available in your router, it's quite simple to get output using remote commands via ssh.
Of course it needs a little tweaking first, but once done, it's very practical

Using Ivan's howto you can achieve the required settings:

Then once it's done, you can run a command from any cli ssh client like this:

ssh -i /path/to/id_rsa user at your_router_address sh proc mem | grep BGP

Subject: [c-nsp] Script to track memory leaks?

Hello routing-people out there,

I am currently trying to track down a memory leak on a Cisco router and I'm wondering whether there is a script out there to collect sh proc mem periodically so that I get the chance to find out which process is leaking. Most likely BGP but who knows.

Of course a script to collect sh proc mem is easy but I thought about one that e.g. generates RRDs from the processlist or something similar.

Don't want to invite the wheel once again.

Thanks
Sascha
