Indluxdb retention manager
If you are collecting a lot of data, you can't keep your influxdb data indefinitely.
Retrieving a lot of data over huge period of time will slow down your queries.
Enter continuous queries, they run every few minutes and write your data with lower precision.
However, continuous queries are pain to setup if you have many measurements and databases.
Influxdb retention manager is operating through two simple steps:
- It will scan database and prepare yaml file for you with all functions which allow you to customise them.
- It will setup your new retention policies and continuous questies which will fill up this new data.
Remaining problems and TODOs
It's not enough to only create retention policies and continuous queries, you actually need to have graph web interface which will support those retention policies and invoke them automatically based on time range selected.
- possible solution within influx itself? https://github.com/influxdata/influxdb/issues/2625
$ ruby irm.rb recon --database my_db
For full list of options, use:
ruby irm.rb help recon
Adjust retention policies if necessary:
Now you can edit yaml file which will be produced by
Create continuous queries
ruby irm.rb create_cq --database my_db
