Network monitoring system with many features.
It can be used for:
- high level monitoring of IT services;
- centralized monitoring of your servers and applications;
- monitoring of SNMP-enabled devices;
- performance monitoring (process load, network activity, disk activity, memory usage, OS parameters etc.);
- data visualization.
- monitoring ›
Zabbix is software that monitors numerous parameters of a network and the health and integrity of servers.
Zabbix server is the central process of Zabbix software.
The server performs the polling and trapping of data, it calculates triggers, sends notifications to users. It is the central component to which Zabbix agents and proxies report data on availability and integrity of systems. The server can itself remotely check networked services (such as web servers and mail servers) using simple service checks.
Zabbix works with Zabbix agent, Zabbix proxy, Zabbix frontend and Zabbix Java Gateway charms.
The functioning of a basic Zabbix server is broken into three distinct components; they are: Zabbix server, web frontend and database storage.

Zabbix server autmatically adds new Zabbix agents to monitoring as empty host (without linked templates) and Zabbix proxies by proxy type (active or passive)
juju add-relation zabbix-server:agent-active zabbix-agent juju add-relation zabbix-server:proxy-passive zabbix-proxy
If relation with Zabbix proxy is destroyed, the charm removes the proxy from configuration and disable all hosts monitored by the proxy.
If relation with Zabbix agent is destroyed, the charm disables host related with the removed relation with Zabbix agent.
There is listed a few major configuration options which can be changed:
Timeout - Spend no more than Timeout seconds on checks processing.
ListenPort - Agent will listen on this port for connections from the server.
DefaultHostGroup - Default Host group for new hosts with active Zabbix agent relations
juju set zabbix-server Timeout=10
Known Issues / Caveates
Zabbix server/proxy can use different database types, so while relation to database is not added, there is no installed Zabbix server/proxy packages.
We recommend to add a relation between Zabbix agent and Zabbix server/proxy after adding relation Zabbix server/proxy with one of available database types.
The charm Zabbix server/proxy supports only MySQL database.
