Python scripts for Zabbix

A collection of various scripts to automate tasks with the Zabbix API. My main goal is to create a set of simple utilities that can be reused in shell scripts without using a lot of curl voodoo.

All of these tools can be invoked with -h/--help to get help.

API tools:

  • zapi.py - Interactive Zabbix API client.

History related:

  • zgethistory.py - Gets values from history for an itemid.

Inv related:

  • zhinvswitcher.py - Switches inv. mode on host(group)s.
  • zgetinventory.py - Prints host inventory in CSV format.
  • zhostupdater.py - Updates host properties.

Item related:

  • zhitemfinder.py - Finds items on a host.
  • zgethistory.py - Get item values from history (Trends are not supported!).

Graph related:

  • zhgraphfinder.py - Finds graphs configured on a Zabbix host.
  • zgetgraph.py - Downloads a graph .PNG from the Zabbix frontend (needs user frontend access) and saves it.

Group related:

  • zghostfinder.py - Finds member hosts in a hostgroup.

Host related:

  • zhostfinder.py - Finds hosts in Zabbix based on search string.
  • zhostupdater.py - Updates hosts properties.

Proxy related:

  • zhproxyfinder.py - Finds configured proxy for a Zabbix host.

Template related:

  • ztmplimport.py - Imports .xml template into zabbix
  • zhtmplfinder.py - Finds linked templates for a Zabbix host.
  • zthostfinder.py - Finds hosts that are linked to a template.
  • zthtmllinker.py - Links host(group)s to a list of templates.
  • zthtmlunlink.py - Unlinks host(group)s from a list of templates.

Trigger related:

  • zhtrigfinder.py - Finds triggers on a host.
  • ztrigswitcher.py- Switches a trigger to enabled or discabled status.

Macro related:

  • zhostupdater.py - Updates host properties.

Event related:

  • zeventfinder.py - Finds events based on filters (includes a tail -f like mode).
  • zgetevent.py - Gets details for eventids, including ack's and alert actions.
  • zeventacker.py - Acknowledges events based on eventids.

Configuration

These programs can use .ini style configuration files to retrieve the needed API connection information. To use this type of storage, create a conf file (the default is $HOME/.zbx.conf) that contains at least the [Zabbix API] section and any of the other parameters:

[Zabbix API]
username=johndoe
password=verysecretpassword
api=https://zabbix.mycompany.com/path/to/zabbix/frontend/
no_verify=true

Setting no_verify to true will disable TLS/SSL certificate verification when using https.

The scripts will need the pyzabbix module, to install:

pip install pyzabbix

For working with graphs (zgetgraph.py specifically) install Pillow (a fork of PIL):

pip install pillow

Usage examples

Save a 1 month 'CPU load' graph starting on the 1st of January 2014 for the host server.example.com as ~/jan.png:

graphid=$(./zhgraphfinder.py -e server.example.com | grep 'CPU load' | cut -d ':' -f 1) ./zgetgraph.py -s $(date --date 'jan 1 2014' +%s) -t 2678400 -f ~/jan.png $graphid

Take note that this requires GNU date.

Using zproxyfinder.py to use the proper Zabbix proxy in a zabbix_sender script.
zabbix_sender -k $ITEMKEY -o $ITEMVALUE -s $HOSTNAME -z $(zhproxyfinder.py $HOSTNAME)
Using zhtmpllinker.py to link 3 templates to all the hosts in a hostgroup:
./zhtmpllinker.py -t "Template App Apache" "Template App MySQL" "Template OS Linux" -G "LAMP Servers"
Using zhtmplunlink.py to unlink a template from all the hosts in a hostgroup:
./zhtmplunlink.py -G "Webservers" -t "Template App MySQL"
Import all .xml templates verbosely from the directory 'templates' and continue with the next template on error.
./ztmplimport.py -v -C ./templates/*.xml

Get the latest item value from history for the item with itemid 1001

./zgethistory.py 1001 -C 1

Get a list of item values with timestamps and unit from history for a period of 2hr from Jan 1st 2014 00:00hr

./zgethistory.py -s $(date --date 'jan 1 2014' +%s) -t 7200 -e 1030

Disable the 'Unavailable by ICMP' trigger on the host named 'Google DNS'

./ztrigswitcher.py -D $(./zhtrigfinder.py -s "Unavailable by ICMP" -n "Google DNS")

Count the number of active triggers on the host 'Webserver'

./zhtrigfinder.py -A "Webserver" | wc -l
Switch the inventory mode to manual for all the hosts in a hostgroup
./zhinvswitcher.py -G "Linux Servers" -m manual
Switch the inventory mode to automatic on all the hosts in Zabbix
./zhinvswitcher.py --all-hosts
Find all the hosts in the 'Customer A' hostgroup that match a name that starts with 'web'
./zghostfinder.py "Customer A" | grep -i '^web.*'
Print the last known value for the available memory in Bytes on the host 'Webserver'
./zgethistory.py -C 1 $(./zhitemfinder.py -k 'vm.memory.size[available]' -n Webserver)
Perform a search for all monitored hosts matching the hostname string 'zabbix'
./zhostfinder.py -m -S zabbix
Output a CSV with hostid, hostname, OS, vendor and contact fields for all hosts in the 'Zabbix Servers' group
./zgetinventory.py -G "Zabbix Servers" -F "os" "vendor" "contact" > report.csv
Update the visible name of the host web001 to 'primary webserver'
./zhostupdater.py web001 -V 'primary webserver'
Enable the host web001, apply the macro {$APACHEPROC} and update the 'Sofware Application A' inv field
./zhostupdater.py web001 -E -M apacheproc=15 -I software_app_a="Apache"
Find all PROBLEM events during the last hour for the the hosts in the group 'Linux Servers' (Limited to 100 events)
./zeventfinder.py -P -t 3600 -G 'Linux Servers'
Acknowledge 3 events with the message "Power outage"
./zeventacker.py -m "Power outage" 6578 6689 6590
Print details on 3 events including trigger comments, actions and acknowledgements
./zgetevent.py -ACL 6578 6689 6590
Acknowledge all PROBLEM events in the last 15 minutes for the hosts in the 'Linux Serves' group
./zeventacker.py -m 'Foobar with Fabric :-(' $(./zeventfinder.py -i -P -t 900 -G 'Linux servers')
Follow Zabbix trigger events for all hosts
./zeventfinder.py -L 10 --all-hosts -f
Using the zapi.py API client to test Zabbix API calls:
Logging in on 'https://zabbix.example.com/' with user 'Admin'.
Welcome to the interactive Zabbix API client.
zapi: z host.get(filter={"host": "Zabbix Server"})
[{u'hostid': u'1001'}]
