Step 2: Configuring Heartbeat
editStep 2: Configuring Heartbeat
editTo configure Heartbeat, you edit the configuration file. For rpm and deb,
you’ll find the configuration file at /etc/heartbeat/heartbeat.yml
. Under
Docker, it’s located at /usr/share/heartbeat/heartbeat.yml
. For mac and win,
look in the archive that you just extracted. There’s also a full example
configuration file called heartbeat.full.yml
that shows all non-deprecated
options.
See the Config File Format section of the Beats Platform Reference for more about the structure of the config file.
Heartbeat provides monitors to check the status of hosts at set intervals.
You configure each monitor individually. Heartbeat currently provides monitors
for ICMP, TCP, and HTTP (see Overview for more about these
monitors). Here is an example that configures Heartbeat to use an icmp
monitor:
heartbeat.monitors: - type: icmp schedule: '*/5 * * * * * *' hosts: ["myhost"] output.elasticsearch: hosts: ["myhost:9200"]
To configure Heartbeat:
-
Specify the list of monitors that you want to enable. Each item in the list begins with a dash (-). The following example configures Heartbeat to use two monitors, an
icmp
monitor and atcp
monitor:heartbeat.monitors: - type: icmp schedule: '*/5 * * * * * *' hosts: ["myhost"] - type: tcp schedule: '@every 5s' hosts: ["myhost:12345"] mode: any
The
icmp
monitor is scheduled to run exactly every 5 seconds (10:00:00, 10:00:05, and so on). Theschedule
option uses a cron-like syntax based on thiscronexpr
implementation.The
tcp
monitor is set to run every 5 seconds from the time when Heartbeat was started. Heartbeat adds the@every
keyword to the syntax provided by thecronexpr
package.The
mode
specifies whether to ping one IP (any
) or all resolvable IPs (all
).See Configuration Options for a full description of each configuration option.
-
If you are sending output to Elasticsearch, set the IP address and port where Heartbeat can find the Elasticsearch installation:
output.elasticsearch: hosts: ["192.168.1.42:9200"]
If you are sending output to Logstash, see Configuring Heartbeat to use Logstash instead.
To test your configuration file, change to the directory where the
Heartbeat binary is installed, and run Heartbeat in the foreground with
the following options specified: ./heartbeat -configtest -e
. Make sure
your config files are in the path expected by Heartbeat
(see Directory Layout). If you installed from DEB or RPM packages, run
./heartbeat.sh -configtest -e
.
