Data Centre Monitoring Tool

A basic tool to monitor the network and servers in a data centre.

What it does (as of now)

• Pings IP addresses
• Tests if SSH is working with the given username and password
• Checks and stores CPU data
• Checks and stores memory utilisation
• Checks and stores disk utilisation
• Checks and stores uptime
• Finds last 5 logged in users

Initial setup for inputs

• Inputs must be in backend/inputs.xlsx
• Column names "IP", "Rack_number", "Username", "Password" must not be changed.
• "IP" should always be the first column
• Make sure there are absolutely no errors in the addresses.
  We have done as much error handling as possible, there might be unhandled cases.

Backend

$ cd backend

Initial setup for database

HBase must be installed (https://hbase.apache.org/book.html#quickstart).\ To initialise the tables

$ python util/tables_init.py

To clear the tables

$ python util/tables_clr.py

The application does not initialise or clear tables by itself.
Before running, make sure tables are initialised.

Usage

• Create input file input.txt as above
• Make sure HBase is running
  (In HBase folder, $ bin/start-hbase.sh)
• Thrift must be running on port 9090
  (In HBase folder, $ bin/hbase-daemon.sh start thrift -p 9090)
• To start daemon processes,

  $ daemon/dcmt.sh start [timeout] [ping and ssh update freq] [snmp update freq]

• To stop daemon processes,

  $ daemon/dcmt.sh stop

• To restart daemon processes,

  $ daemon/dcmt.sh restart

• To start flask app,

  $ python flaskapp.py

• Outputs are stored as in tables 'snmp', 'ping' and 'ssh' in HBase
• Daemon output and errors stored in daemon/dumps
