[Leaf-user] SNMP Monitoring of Dachstein
I have some basic SNMP monitoring of my Dachstein machines working using the old SNMP package and MRTG. With these I keep a constant graph of the activities of eth0, eth1 and ipsec0 on both ends of my test VPN tunnel. I converted to net-snmp and everything is still working (thanks people for standards). My next task is to add monitoring of the memory, CPU, and RAM disks. The result would be a single web page which provides a continuous graph of the health of the LEAF boxes. You can see at a glance where something may be going wrong. Since MRTG also does such a nice job of keeping a running summary of the data on a daily, weekly, monthly and yearly basis. You can also use the data to predict when you may need to make changes on a system. Others have setup MRTG to do this kind of thing on their Linux servers. I was wondering if anyone here have already done something similar and have some MRTG scripts that work with the net-snmp mibs that they can share, or maybe just some pointers. When I'm done I'll give what I have to Charles. He needs some more packages to fill up that Dachstein CD. ;-) Roger ___ Leaf-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-user

I haven't actually switched to net-snmp yet (although I have verified it's working), although the intent is to be able to monitor things like CPU web-server load. I've also started playing with OpenNMS (http://www.opennms.org), but don't have anything working yet...looks pretty cool, though.

Maybe this is out of line here, or maybe not. Here we use NetSaint to monitor many systems. It would be quite simple to set up a monitoring system to check for CPU, disk space, memory - whatever you want. All you need is an ssh server on the LEAF side and scripts that give one line of info and return 0 for OK, 1 for WARNING, and 2 for CRITICAL Then you run your script using SSH. Of course, NetSaint is for system critical conditions, and isn't for performance monitoring, though the latest versions offer the ability to store performance data (but not process it). MRTG is more of a history, and NetSaint is a snapshot in time. Sort of like the difference between a balance sheet and an income statement :) ___ Leaf-user mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/leaf-user
