Monitoring Linux (CentOS) Hosts

ru flag

I'm using PRTG as my main monitoring solution. This may sound simplistic but there doesn't seem to be an easy built in way to monitor everything "bad" on a Linux host including

  • Degraded RAID (software RAID)
  • Failing RAM
  • Failure of postgres to replicate
  • Common environmental such as high load, low memory, full disk
  • Incrementing counts of random 'errors' in VLM.

Is there a daemon I can run on the host that has a bunch of pre-built "things to look for" and will automatically send SNMP traps to PRTG? I just feel like I'm reinventing the wheel here with custom scripts to do things like check for degraded software RAID.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
