Periodic Slow Response 2821 (300+ms, 1 minute)

ironman · ‎03-11-2011

This could be LAN or WAN I believe...

My solarwinds NPM reports very slow response times from my satellite clinic.

Often times it is 300ms to 600ms when it should be 10-15ms.

CPU does not seems to spike, the memmory does not seem to spike

The bandwidth does not spike.

It happens mostly during work hours about 10 times a day

Solarwinds reports the delay and then 2 minutes later it reports normal activity

I have broadcast/multicast control on the switches

We have static route for our network meaning no routing protocols

We have 12 other clinics with the same configs and they are fine

I have double checked the configs but I am not holding my breath on that item

I have rebooted the router without affect

I have not replaced the cable to the demarc on either side of the WAN connection

I have not reseated the service provider T1 cards

I have not reseated the T1 card on either router

Any thoughts?

All the best and thank you in advance,

Review Interface counters. if there is a serial link - review the controllers as well for any errors/clocking issues.

Please do a standard ping test with 1500 byte size packets on the wan link. How long does the incident last? If there is a 1-2 minute time period, During the issue this ping test will help narrow down the issue.
