what do you like? We have been using NAGIOS v1 forever, and our old system can't support going to a higher revision. I am also working on the assmption I can use SNMP for everything, I really want to skip the additional load of NRPE + nagios-plugins on every host. Back to question one: what do you like? I am beating on OpenNMS right now, very large package and requires a fair bit of resources (which I have available thankfully). I am beaing on, and not liking, Zenoss Community. I have a query into them for their enterprise version to see if it is a better solution. I need to be able to monitor for normal things: ICMP of a server - simple, easy, effective. Port monitoring - like HTTP or SSH. Disk utilization including thresholding for alerts. General geeky graphing of whatever. -- Mike Horwath ipHouse - Welcome home!
