    • Type: Incident report
    • Resolution: Cannot Reproduce
    • Priority: Minor
    • None
    • Affects Version/s: 2.2.11
    • Component/s: Agent (G)
    • None
    • Environment:
      Ubuntu 12.04.5

      Attempting to monitor a very large partition:

      # df -h /srv/ams/media
Filesystem            Size  Used Avail Use% Mounted on
/dev/mapper/vg_kimstream02_data-lv_data
                      2,0T  1,4T  516G  74% /srv/ams/media

      or in bytes:

      # df -B1 /srv/ams/media
Filesystem               1B-blocks          Used    Available Use% Mounted on
/dev/mapper/vg_kimstream02_data-lv_data
                     2164338376704 1500130099200 554259423232  74%

      but the request from the Zabbix server fails:

      # zabbix_get -s xxx.xxx.xxx.xxx -k vfs.fs.size[/srv/ams/media,pfree]
ZBX_NOTSUPPORTED

      The Item's 'Data type' is set to Integer and 'Units' is set to B (byte). According to Zabbix documentation a Numeric (unsigned) is a 64bit unsigned integer, therefore 2^64 (18,446,744,073,709,551,616) is larger than 1,500,130,099,200.

      Why does Zabbix fail in this case to return the partition size?
