   1 Zabbix plugin
   2 =============
   3
   4 The Zabbix plugin actively sends information to a Zabbix server like:
   5
   6 - Ceph status
   7 - I/O operations
   8 - I/O bandwidth
   9 - OSD status
  10 - Storage utilization
  11
  12 Requirements
  13 ------------
  14
  15 The plugin requires that the *zabbix_sender* executable is present on *all*
  16 machines running ceph-mgr. It can be installed on most distributions using
  17 the package manager.
  18
  19 Dependencies
  20 ^^^^^^^^^^^^
  21 Installing zabbix_sender can be done under Ubuntu or CentOS using either apt
  22 or dnf.
  23
  24 On Ubuntu Xenial:
  25
  26 ::
  27
  28     apt install zabbix-agent
  29
  30 On Fedora:
  31
  32 ::
  33
  34     dnf install zabbix-sender
  35
  36
  37 Enabling
  38 --------
  39
  40 Add this to your ceph.conf on nodes where you run ceph-mgr:
  41
  42 ::
  43
  44     [mgr]
  45         mgr modules = zabbix
  46
  47 If you use any other ceph-mgr modules, make sure they're in the list too.
  48
  49 Restart the ceph-mgr daemon after modifying the setting to load the module.
  50
  51
  52 Configuration
  53 -------------
  54
  55 Two configuration keys are vital for the module to work:
  56
  57 - zabbix_host
  58 - identifier (optional)
  59
  60 The parameter *zabbix_host* controls the hostname of the Zabbix server to which
  61 *zabbix_sender* will send the items. This can be a IP-Address if required by
  62 your installation.
  63
  64 The *identifier* parameter controls the identifier/hostname to use as source
  65 when sending items to Zabbix. This should match the name of the *Host* in
  66 your Zabbix server.
  67
  68 When the *identifier* parameter is not configured the ceph-<fsid> of the cluster
  69 will be used when sending data to Zabbix.
  70
  71 This would for example be *ceph-c4d32a99-9e80-490f-bd3a-1d22d8a7d354*
  72
  73 Additional configuration keys which can be configured and their default values:
  74
  75 - mgr/zabbix/zabbix_port: 10051
  76 - mgr/zabbix/zabbix_sender: /usr/bin/zabbix_sender
  77 - mgr/zabbix/interval: 60
  78
  79 Configuration keys
  80 ^^^^^^^^^^^^^^^^^^^
  81
  82 Configuration keys can be set on any machine with the proper cephx credentials,
  83 these are usually Monitors where the *client.admin* key is present.
  84
  85 ::
  86
  87     ceph config-key set <key> <value>
  88
  89 For example:
  90
  91 ::
  92
  93     ceph config-key set mgr/zabbix/zabbix_host zabbix.localdomain
  94     ceph config-key set mgr/zabbix/identifier ceph.eu-ams02.local
  95
  96 Debugging
  97 ---------
  98
  99 Should you want to debug the Zabbix module increase the logging level for
 100 ceph-mgr and check the logs.
 101
 102 ::
 103
 104     [mgr]
 105         debug mgr = 20
 106
 107 With logging set to debug for the manager the plugin will print various logging
 108 lines prefixed with *mgr[zabbix]* for easy filtering.
