EEM Script to reset Dspfarms nightly

[lstonesi]

Hello,

I have been unsuccessful on my own in creating a EEM TCL script to catch, log and reset dspfarms that are down on a nightly basis.

This can be a EEM tcl script or applet that do the following:

1. Run the following command: "show sccp all | Begin MTP"

2. From the outout catch the Profile Identifier of the DSPFarm(s) that have KEEPALIVE_FAILED.

3. Log or append to flash file: If a failed DSPFarm was found log the date and Profile Identifier to the flash file.

4. Email the system admin that Profile Identifiers X, Y and Z were reset.

5. Reset the DSPFarms with KEEPALIVE_FAILED.

Here is an example of the "Show sccp all | Begin MTP" - The actually output is very large.

#    MTP Oper State: ACTIVE - Cause Code: KEEPALIVE_FAILED

Commands to reset the dspfarm profile:

#        WAIT XXX AMOUNT TIME

#        cli_exec $cli(fd) "enable"

#        cli_exec $cli(fd) "configure terminal"

#        cli_exec $cli(fd) "dspfarm profile " + $IDENT     <---- the Profile Identifier

#        cli_exec $cli(fd) "shutdown"

#        cli_exec $cli(fd) "no shutdown"

#        cli_exec $cli(fd) "end"

I would also have to run a command that would limit the EEM TCL or Applet from using all the memory resources on the router. This script will run on a 3945 with 15.0 and 15.1.

Hopefully, someone can help out with this. My attempts have failed and caused router reloads hence the requirement for memory management.

Thanks,

Lee

A small update:

5. Reset the DSPFarms with KEEPALIVE_FAILED at 1:00 am nightly.

This script should do what you want.  It requires you to set one environment variable in addition to the standard set of email variables like _email_server, _email_from, etc.

This will control where the log file is stored:

event manager environment dspfarm_log flash:dspfarm.log

Thanks for your help Joseph.

This script did the trick.
