<![CDATA[Timescale DB]]>If I want to migrate from Mysql to Timescale is there any way to import the data from mysql ?  By the way awesome choice 🙂  I always thought timeseries databases where better suited for NMS's   

Thanks

The NetXMS database schema is different for TimescaleDB (even from Postgres -> TimescaleDB), so you'd have to use nxdbmgr for the migration. It's meant to support migration to TimescaleDB from 2.2.14 onwards (haven't tried it yet, we're still running load tests and comparisons between TimescaleDB and Postgres, feeding 50-60GB of live data into each system per day to compare performance).
One thing to note on TimescaleDB use, from what I can tell NetXMS configures the Hypertables with a 1 week chunk interval by default. Depending on your data ingestion rate, you may want to change that before you go live (e.g. for our test, I changed it to 1 day).

When feeding 50-60GB of data per day , that represent how many devices/instance ?

That was for testing purposes only. I configured a number of firewalls to generate verbose syslog messages on everything and had them send those to the test system, in addition to creating a range of "poll every 5 seconds" DCIs.
So it was live data, but not something I'd for a live system. Can't really compare that to a number of nodes.

As Victor said, TimescaleDB support is much improved in version 3. I'd suggest waiting for the release or upgrading to version 3 (beta version in 'unstable' repository) if you intend to use it now.

Best regards,
Victor

Enterprise is not something we're considering at our end at this stage, but other NetXMS users might?
