DMA Alarms: Cassandra – DataBase Storages in File Offload mode

Solved1.51K views28th November 2022adl2099 Cassandra offload mode storages

Alberto De Luca [DevOps Enabler]4.58K 25th November 2022 0 Comments

Spotted this kind of error in a local cassandra deployment (no cassandra cluster, DB on the DMA):
what's the impact on the DMA when one or more "storages" go to offload mode?

Is it correct to configure this as a critical alarm? Or should it be some lower severity?

Any steer will be helpful - thanks

Do you not have any offload configuration of the database? Please note that recent versions of the DataMiner support file-based offload mechanism.

Offload database | DataMiner Docs

"From DataMiner 10.2.0/10.1.1 onwards, it is possible to offload data to a file in the local system cache folder instead of to an offload database. You can do so by going to System Center > Database > Offload and selecting File in the drop-down box at the top. Below this, you can then configure the data offloads (see Configuring data offloads) and set a maximum size for the combined offload files."

Below is an example screenshot for File offload configuration from a DMA.

Thanks.

Thank, Srikanth – I believe this doesn’t apply to the above case – the alarms are related to internal Cassandra storages (no cluster either, so in this case it is the local DB)

Not a problem Alberto. Wording looks so similar, so I thought this may be to do with the file offload configuration.
