Hello All,

Where does vertica take all this info from ?
1. IP :
2. em1 :
3. p2p1 :
4. Name :
5. Total Mem :
6. Disk utiliztion :
7. CPU Count:
8. Hostname :

Also what does em1 / p2p1 stand for..
I tried to track the simplyfast.py but could not find it in /opt/vertica/oss/python/bin/python

Is this the only script which completely controls the MC.

Actually I am seeking answers to this because the all the above detail in my cluster are slightly different on all nodes....i.e. one has a some details but other has all details.

MC gets data from the data_collector process.

data_collector is also a table.

Select * from data_collector;

In that list, you'll see all the tables that store data (the dc_* tables) that MC uses to pull information for its various reports. For example, dc_info_by_minute has IO information aggregated by minute. There are about 100 of these tables.
