Solved: Re: EEM to help with latency spiking issue

kevinhobson2000 · ‎12-24-2010

Hi,

I am looking to create an emebedded event manager that checks a ip sla's rtt and when it goes above a certain threshold intitates a trace and stores it in a file on flash.

Can anybody help with this?

Cheers

Kev

Attached is an EEM Tcl policy that should do what you want. It requires you to set a few environment variables first.

# rtt_collector_id     : IP SLA collector ID to watch.
#
# rtt_threshold        : Round-trip response time threshold in milliseconds
#
# rtt_poll_freq        : The number of seconds between each polling interval.
#
# rtt_dest_ip          : The IP address to which the traceroute will be run.
#
# rtt_output_file      : File to store the output of the traceroute.

When it runs, a syslog message will be sent to indicate that the traceroute output was saved to the specified output file.

By trace, do you mean a traceroute? What version of IOS are you using?

Hi Joseph,

Yes i mean traceroute.

IOS version is: 12.4(11)T4

Thanks for your help with this.
