Lower time frame monitoring

We seem to be having issues at our call centers where calls are getting dropped by several agents at a time.  When this happens, the MSP that helps us sees on Cisco RTM the CUCM servers will lose communication with each other for just a couple of seconds.   They see SDLLinkOutOfService in the logs between our call manager servers.  We have three CUCM servers at our HQ and 3 at our Colo.   But we don't have anything in place at that low a of  time frame to catch such a small event.  Can VNQM be configured in some way for certain connection between devices to do more real time monitoring and dump anything older than a configured time interval, like 30 minutes or something.   Just need data held long enough to go and research right after it happens.  Or is this something that VNQM does automatically?   We don't have VNQM on our SW server currently, but if it can accomplish this, I will make a case for adding it.  And if it can't does anyone know of another product that can accomplish this?
