Best Server Monitoring Software (Free / Cheap)

Looking for a solution to monitor both the network side of things and the process side of things.
I've looked at things like Zenoss and Nagios but ideally I'd like something relatively easy to set up and that can alert me to processes failing or crashing.
Any ideas?

Observium. Takes a while to setup but once it's up it works very well
i have a monitoring platform elasticTrace which u can try out i just dont have alerts until an upcomming relase.
zenoss and nagios a little bit hard.
Try observium, or newrelic.
@rmlhhd I've install observium but can't quite figure out SNMP communities? Any tips or good places to look. I've googled it but a lot of the results are about cisco routers
@mpkossen did a tutorial on Observium: http://lowendbox.com/blog/observing-devices-with-observium/ and http://lowendbox.com/blog/observing-devices-with-observium-adding-a-device/
I was stucked at first time there too.
Just do step by step this guide.
All what you need to understand:
1.) Install smtp on your server what you want to monitore.
2.) if you have observium on the monitored host install smtp-node and smtp-server part (forgot their real names). And configure like it must to work.
Then, you must install php on your server.
And you need try to use php files to "grab" data from your server. It is just a simple command what will "call by smtp to your server to read info about some characteristics"
sorry for double posting, i hope this helps you, because as i said before i was stucked only at smtp too: http://lowendtalk.com/discussion/20728/help-me-to-understand-observium-snmp-protocol
@neqste Got it up and running! looks really nice so far. Added 5 servers just waiting for it to poll.
You can do that manually
@joelgm just figured that bit out and changed the cron to poll a bit more frequently! Thanks for everyone's suggestions / help
you can poll it by command in terminal ./poll*blabla forgot the name.
Inside your observium directory:)
do you mean smtp or snmp?
Observium is good, recently I move stuff from munin to observium, deactivating all munin instance and I can save some resources
as it used SNMP as along as it configured, you can use any tool/apps that can read SNMP data (don't have to be observium.
I do not know English.
I often confuse the word. But you understand me correctly. I meant snmp
Try uptimerobot service.
Been using it for long time.. happy with them.
It is possible to monitor the same node Observium is hosted on, right? I keep running into some issue with SNMP community.
anything that is similar to Linode's LongView?
why not try snmp v1?
Doesn't work either, think I'm doing something wrong here.
PM me the contents of your /etc/snmp/snmpd.conf file and I'll have a look.
Also, is the node OVZ or Xen?
tried Nagios too, but it doesn't seem to be easy for setup at all.
OVZ, I will PM you the details in couple minutes.
Edit: nvm, think I figured it out.
a pile of resource I collected for observium, you can have a look.

Thank you, it seems like there was an issue with the snmpd.conf that I used from LEB tutorial. This seems to work just fine:
Are you guys monitoring servers over the internet with observium (opening up snmp port 161 to all)? Or are you using for example iptables to restrict who can query your server?
The one Observium recommends as a starter is:
@Nekki - Yeah, that's the one I used. Everything seems to work so far.
observium have really bad guide at their website:) Most hard installing monitoring tool ever:) I'm remember, i was stuck a lot with snmp:)
I thought it was very easy to follow, done it twice no issues.
Well, I don't think it's that difficult, just the part with SNMP could be explained a little bit more in depth, other than that it's just fine.
anything except SNMP very easy to do. Only snmp hard part:)
