InfluxDB#
InfluxDB is a time series database for storage and retrieval of data in fields such as operations monitoring, application metrics, sensor data, and real-time analytics. InfluxDB and the associated Telegraf agent will be used to collect server metrics from the cluster’s systems and applications.
Operating Systems#
These guides are written for Red Hat Enterprise Linux 8 based operating systems and are compatible with AlmaLinux 8 and Rocky Linux 8.
Access Controls#
The InfluxDB node should only be accessed directly using SSH by system administrators. Standard cluster user accounts should not be able to SSH into the InfluxDB node.
The InfluxDB application manages application level access.
Hostnames#
These guides use the following example Hostnames and FQDN for InfluxDB. FQDNs can be provided by utilizing a DNS server or installing a hosts file on the system itself.
Note
An example /etc/hosts file has been provided: hosts
