Linux Collector Agents

The following basic agent types are provided:
  • CPU usage %
  • Memory Free %
  • Disk Free space %
  • Disk IOs
  • Network IOs

All of them supports both Username/password and Private key file authentication.

Using private key file

For those not familiar how to set up private/public key authentication for SSH the following is a very basic guide.
This assumes you are running a Windows machine connecting to a Linux machine.
1. Download and install Putty ( http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html )
2. Run Puttygen (on the Windows machine that you are trying to connect from) and use Generate key function. Specify a passphrase (and remember what it is of course...)
3. Save/Export Private key to a secure place. Same with Public key.
4. For the purpose of using QuickMon (SSH.Net) you will also need to Export a converted key. Use the Conversion -> Export ssh.com menu option. THIS is the file that you will be specifying in QuickMon to pass to the SSH server (Linux machine)
5. For the Linux machine (SSH server) to accept the generated key you must copy the key content as displayed in the PuTTY Key Generator (everything from 'ssh-rsa' up an until the double equal signs '==') and paste it in the authorized_keys file of the specified user on the Linux machine.
6. On the Linux machine the SSH server must be installed and running (openssh or so).
7. In the required user's home directory '~' create a '.ssh' directory if it doesn't exist yet. Inside this directory there must be a authorized_keys (or authorized_keys2 if you use SSH-2) file file where you have to paste the key as displayed in PuTTY Key Generator. Important! Make sure the whole entry is a single line with not line breaks (\r\n). Each key must be on its own line.

There are more detailed guides on the Internet how to set up SSH and keys if this is not enough.
