EMC VMAX and TDEV monitoring
STOR2RRD does not monitor TDEVs. However Storage Groups are monitored, let us explain why:
- There could be tenth of thousands TDEVs, it is a lot of data for storing and presenting
- It would require to issue tenth of thousands REST API queries to get such data regularly (every 5 minutes).
We are not sure if this is something what Unisphere can cope with it.
We have bad experiences with other storage if we use a lot of queries regularly, we need to reduce/optimize number of queries often
- Tenth of thousands items in single aggregated graph is for nothing, no one reads it.
- STOR2RRD idea behind is not monitor everything possible to get all information, from all levels.
ST0R2RRD wants be a front-end tool which should highlight problems and which allows debugging into some level.
To get low level details you need to use native tools. We do not want to be a full replacement of native low debugging tools.
