Zabbix server is giving same value for all linux servers upon disk space monitoring using Zabbix Active Agents. I am using Zabbix server 3.2. Please help.

  • Please go to Monitoring -> Latest Data -> Name like "Free disk space" -> Filter -> tell us the key names, intervals, type, last check, last value. Just edit your question. – kubanczyk Mar 23 '18 at 23:03
  • Hi @kubanczyk, Here is what I have: Name: File Systems: Free disk space on / (percentage), Last Check: 2018-03-23 19:49:36. Last Value: 51.8%. All values are same in all hosts. I was supposed to receive different values. – user427751 Mar 23 '18 at 23:52
  • The key names are like `vfs.fs.blabla` please tell those. And. Please. Edit. All. Of. It. Into. Your. Question. – kubanczyk Mar 24 '18 at 08:59
  • Hi @kubanczyk , Here is the detail information I have: Parent items: Template OS Linux Active ⇒ Template App Zabbix Agent Active, Name: Free disk space on $1 (percentage), Type: Zabbix agent, Key: vfs.fs.size[{#FSNAME},pfree], Host interface: 0.0.0.0:10050. – user427751 Mar 25 '18 at 15:39

Most likely your agents are misconfigured - check the agent configuration file, parameter Hostname. This is the host which will get the value. The value of this configuration parameter must match the host name - not IP, not DNS. In this case, it sounds as if you have one or more agents sending data with various Hostname values.

Looks like it was template that was misconfigured - the item was passive, not active.

  • Hi @Richlv, Thanks for your quick response. Hostname in all server seems correct and agents are sending correct data for memory and swap space but not the correct disk storage space value. I could not understand what else could go wrong. I have double, triple checked hostnames on zabbix agents and server. – user427751 Mar 23 '18 at 19:56
  • Hmm, in that case please add info on what values you are getting and what you are expecting. – Richlv Mar 23 '18 at 23:39

  • What's the item type for that item? Is it "Zabbix agent" by any chance, and is it maybe reporting diskspace on the Zabbix server? – Richlv Mar 24 '18 at 03:37
  • Hi @Richlv , It is actually "Zabbix agent" on item type. – user427751 Mar 25 '18 at 15:40
  • Your configuration is broken. "Zabbix agent" is the passive type. Most likely it is querying the same IP address/DNS name, as set in your hosts in the interface. If you really want to use active items, change it to "Zabbix agent (active)" in the template. – Richlv Mar 25 '18 at 20:54
  • Hi @Richlv, That works. Thank you so much for your help. – user427751 Mar 26 '18 at 21:35
