RE: [SA-list] SNMP checks

[Jack Lyons]

I have a perl check that will store the previous value and then compare it to the next value.  It uses the OID and ActiveState Perl and Net::SNMP   You can find it: http://www.lyonsonline.net/jack/Projects/snmpdelta/ Let me know if it works or if you need help getting it working   Jack   -----Original Message----- From: Dirk Bulinckx [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 17, 2004 4:37 PM To: [EMAIL PROTECTED] Subject: RE: [SA-list] SNMP checks   Currently not.   Dirk.     From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Robb Fesig Sent: Tuesday, February 17, 2004 7:22 PM To: [EMAIL PROTECTED] Subject: [SA-list] SNMP checks Is there anyway we can compare an SNMP value to a previously retrieved value in order to alarm on a comparison?   Example: Router S0 Error Count on 1st check: 8800 Check if change greater than 10 alarm - difference unknown, no alarm Router S0 Error Count on 2nd check: 8802 Check if change greater than 10 alarm - difference of 2 found, no alarm Router S0 Error Count on 3rd check: 8840 Check if change greater than 10 alarm - difference of 38 found, alarm sent Router S0 Error Count on 4th check: 8841 Check if change greater then 10 alarm - difference of 1 found, no alarm   Would this be possible, because it would be a great advantage to us to monitor line errors this way. If it's not possible, does anyone on the list have a suggestion that would work?     Thank You, Robert Fesig, Network Engineer American Computer Associates, Inc.
