Subject: NDS2 updates 

We had several problems with our NDS2 server configuration. It runs on megatron, but I think it may have had issues since perhaps not everyone was aware of it running there.

  1. channel lists were supposed to updated regularly, but the nds2_nightly script did not exist in the specified directory. I have moved it from Joe Areeda's personal directory (/home/nds2mgr/joework/server/src/utils/) to nds2mgr/channel-tracker/.
  2. The channel history files (/home/nds2mgr/channel-tracker/channel_history/) are stored on the local megatron disk. These files had grown up to ~50 GB over tha past several years. I backed these up to /users/rana/, and then wiped them out so that the NDS could regen them. Now that the megatron local disk is not full, it seems to work in giving raw data.
  3. Need to confirm that this serves up trend data (second and minute)
  4. I think there is a nds2-server package for Debian, so we should update megatrons OS to the preferred flavour of DebIan and use that. Who to get to help in this install?

Since Megatron is currently running the "Shanghai" Quad-core Opteron processor from ~2009,  its ~time to replace it with a more up to date thing. I'll check with Neo to see if he has any old LDAS leftovers that are better.
