New device's items have high usage in the value cache until zabbix server restart

XMLWordPrintable

    • S24-W14/15, S24-W16/17
    • 1

      Steps to reproduce:

      1. Add a device as follows:
      2. Check value cache

      Result:
      Permanently increasing values in the value cache for items with triggers using either min, avg or max functions with time in the parameters on the new hosts. Resulting in Zabbix value cache working in low memory mode alert (See value-cache-server-log.txt for zabbix_server.log output after adding 6 new devices. I have mapped the item id to the device and item name)
      Restart brings the values back to normal amounts. (See value-cache-post-restart.txt for post-restart value cache command output)
      Expected:
      Value cache to be cleared after maximum time parameter in triggers

      Further:
      New devices were added as follows (used in the value cache server log output):

      1. 2024-03-14 16:40:38 Host Device 1 added
      2. 2024-03-14 16:40:39 Host Device 2 added
      3. 2024-03-14 17:28:00 Host Device 3 added
      4. 2024-03-14 17:28:01 Host Device 4 added
      5. 2024-03-15 16:08:40 Host Device 5 added
      6. 2024-03-15 16:08:40 Host Device 6 added
