Considerations for monitoring the 1.x TICK stack
One of the primary use cases for InfluxData’s TICK stack is infrastructure monitoring, including using the TICK stack to monitor itself or another TICK stack. These are the two main approaches to Monitoring your TICK stack:
- Internal monitoring - A TICK stack that monitors itself.
- “Watcher of watchers” approach - A TICK stack monitored by another TICK stack.
By default, the InfluxData platform is configured to monitor itself.
Telegraf collects metrics from the host on which it’s running for things such as
CPU usage, memory usage, disk usage, etc., and stores them in the
telegraf database in InfluxDB.
InfluxDB also reports performance metrics about itself, such as continuous query statistics,
internal goroutine statistics, write statistics, series cardinality, and others,
and stores them in the
For the recommendation about
_internal databases, see Disable the
_internal database in production clusters below.
Pros of internal monitoring
Internal monitoring requires no additional setup or configuration changes. The TICK stack monitors itself out of the box.
Cons of internal monitoring
No hardware separation
When using internal monitoring, if your TICK stack goes offline, your monitor does as well. Any configured alerts will not be sent and you will not be notified of any issues. Because of this, internal monitoring is not recommended for production use cases.
The “watcher of watchers” approach
Recommended for production environments.
A “watcher of watchers” approach for monitoring InfluxDB OSS and InfluxDB cluster nodes offers monitoring of your InfluxDB resources while ensuring that the monitoring statistics are available remotely in case of data loss.
This usually takes the form of an Enterprise cluster being monitored by an OSS TICK stack. It consists of Telegraf agents installed on each node in your primary cluster reporting metrics for their respective hosts to a monitoring TICK stack installed on a separate server or cluster.
For information about setting up an external monitoring TICK stack, see Setup an external monitor.
Pros of external monitoring
With a monitor running separate from your primary TICK stack, issues that occur in the primary stack will not affect the monitor. If your primary TICK stack goes down or has issues, your monitor will be able detect them and alert you.
Cons of external monitoring
Slightly more setup
There is more setup involved with external monitoring, but the benefits far outweigh the extra time required, especially for production use cases.
_internal database in production clusters
InfluxData does not recommend using the
_internal database in a production cluster.
It creates unnecessary overhead, particularly for busy clusters, that can overload an already loaded cluster.
Metrics stored in the
_internal database primarily measure workload performance,
which should only be tested in non-production environments.
To disable the
_internal database, set
false under the
[monitor] section of your
