Deploy TSDB Service on a Separate Node

TSDB contains information related to real-time telemetry events from platform infrastructure, JMX events, and Spark executor or driver JVM usage timeline.

The TSDB standalone installation gives you the choice of running a single TSDB instance that hosts both systems and Spark Graphite Metrics Data events or running two distinct TSDB instances on the same or different hosts.

Follow the steps to make the TSDB a required option.

Single Standalone TSDB

Follow the steps as performed earlier with Install Pulse on Single Node (Docker/Podman-Based).
Run the following commands on the host that is being used for standalone TSDB.

[root@pulse2:~ (ad-default)]$ accelo deploy addons INFO: Active Cluster: pulse_demo ? Select the SA components you would like to install: [Use arrows to move, space to select, type to filter] > [ ] FS Elastic [ ] LogSearch [x] STANDALONE TSDB [ ] FS Analytics V2 [ ] STANDALONE DB [ ] HA GraphQL [ ] LDAP

Type the active cluster name, and select FS Elastic.

Login to the Pulse server and open the main Pulse configuration file present at _ACCELO_HOME/config/acceldata_cluster_name.conf_. Update the influx hostname in every placeholder:

influx = [ { name = "default" host = "<influx_host_name>" port = 19009 username = "<username>" password = "<password>" dbName = "<db_name>" }, { name = "kafka" host = "<influx_host_name>" port = 19009 username = "<username>" password = "<password>" dbName = "<db_name>" }, { name = "graphite" host = "<influx_host_name>" port = 19009 username = "<username>" password = "<password>" dbName = "<db_name>" }, { name = "nifi" host = "<influx_host_name>" port = 19009 username = "<username>" password = "<password>" dbName = "<db_name>" }, { name = "dsConnection", host = "<influx_host_name>" port = 19009, username = "<username>" password = "<password>", encrypted = false, dbName = "<db_name>" } ],

Login to the influx host and connect to Influx db shell for creating databases for SYS, Kafka, Spark, DB names to be used as specified on above Pulse app configuration file.
Login to Pulse core server for updating all Pulse agents to new TSDB, update influx hostname on override.yml file.

base: graphite_influxdb_urls: http://<NEW_TSDB_HOSTNAME>:19009 influxdb_urls: http://<NEW_TSDB_HOSTNAME>:19009

On Pulse-core server run the following command to apply the configuration changes.

accelo reconfig cluster -a

Run the push config command on Pulse core server to push the updated config changes in application config file. Press Y on any prompts.

accelo admin database push-config -a

Restart all the Pulse services.

accelo restart all
