SSH CPU Utilization Monitor
Hello,
I've configured a CPU Utilization to ssh and I'm seeing a SSH connection being made to my Linux servers as the the tcpdump:
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode
listening on eth0, link-type EN10MB (Ethernet), capture size 96 bytes

The syslog message on the Linux server is:
Oct 7 21:56:04 linux-server sshd(pam_unix)[9245]: session opened for user donbala by (uid=0)
Oct 7 21:56:09 linux-server sshd(pam_unix)[9245]: session closed for user donbala
However the Test Monitor gives me the following:
Test results
The Monitor did not respond to the test request
Summary
Device Name linus-server
Monitor Name CPUUtilization
Protocol CLI
Command top b n 1 | grep 'CPU[0-9]* states:'
Possible reasons
1. The device might be down.
2. The username and password provided for this device might be wrong.
3. Telnet/SSH service might be down
4. The connection to Telnet/SSH session might have Timed-out
What I'm doing wrog??
