Recently, I noticed that my home internet performance was patchy so I decided to investigate further. To observe how my ADSL sync rate performs over time, I created an EEM script to monitor it and log when it falls below a certain rate. Now that I've got this working, I'd like to share this with the Cisco community in case anyone else finds this useful.
I'm using a Cisco 877 with 15.1M(6) IOS.
Generally, I get a sync rate around 8Mbps which I can verify via 'show dsl int atm0'. I wanted to check this every 30 mins and when it fell below 4Mbps to generate a syslog.
My configuration:
----------------------------------------------------------------------------------------------------
snmp-server community public RO
!
event manager applet ADSL_SPEED
event snmp oid 1.3.6.1.2.1.10.94.1.1.2.1.8.11 get-type exact entry-op lt entry-val "4000000" poll-interval 1800
action 1.0 syslog priority notifications msg "ADSL sync speed has fallen below 4Mbps"
exit
exit
----------------------------------------------------------------------------------------------------
The SYSLOG output looks like this:
router#show log | in EM
Jul 4 15:22:31: %HA_EM-5-LOG: ADSL_SPEED: ADSL sync speed has fallen below 4Mbps
router#
I hope people out there find this useful :-)
