EEM Scripting for error and drop counters

Hi,

We want to check the following counters for drops every 5 minutes and generate an alarm if a certain threshold of errors (example: increment of 100 in the error/drop counters in the last 5 minutes) is overcome:

My sample script is inline, i'm missing how to parse and generate the alarm if the threshold is surpassed:

Example command:

SPLAB_7600_3#remote command module 4 show platform hardware drops | include Selene|drp                

------ Selene 0 Channel 0 ------

Selene Ingress Drop Counters Ch[0]

Selene Egress Drop Counters Ch[0]

    egr_tot_fifo_drp_ctr                          25

Selene Drop Counters

------ Selene 1 Channel 0 ------

Selene Ingress Drop Counters Ch[0]

Selene Egress Drop Counters Ch[0]

Selene Drop Counters

Best Regards,

Afonso

EEM Scripting for error and drop counters

I believe this is what you are looking for:

set egr_drp_ctr $result

expr {$egr_drp_ctr + 100} sumof

if {$egr_drp_ctr >= $sumof}

    puts "Alarm"

It may need correction on the syntax , but thats the logic.
