Linux, Unix and Device Monitoring

PA Server Monitor has great support for monitoring Unix-based operating systems like Linux, and network devices like routers and firewalls. This is accomplished using standard protocols:

CPU & Memory can be monitored using the standard Performance Monitor. When it detects that it's not communicating with a Windows server, it switches to SNMP in the background and simulates Windows CPU and memory counters.
Disk Space can be monitored with the standard Disk Space Monitor. It too will switch to SNMP in the background and display disk volumes for monitoring.

Bandwidth is monitored and charted using the standard SNMP monitor by watching ifInOctets and ifOutOctets. The Smart Config process will automatically create a bandwidth monitor if those SNMP objects are found.
Ping Response monitoring can be directed at anything with an IP address. Reports and alerts are naturally supported too.
The Process monitor uses SNMP behind the scenes to verify the specified processes are running on Linux/Unix.
Direct SNMP monitoring can be applied to anything that supports SNMP. Our MIB parser makes it simple to browse through the SNMP objects of a device.
SNMP Traps can be received from any device, filtered, alerted on, and reported on.
Syslog events can be received from any device. You can choose which ones to alert on. Reporting is also supported.
Web Page monitoring can be done for web pages served from any HTTP server.
The Mail Server monitor checks SMTP, POP3 and IMAP4 servers regardless of server operating system.
Monitoring FTP servers works fine using the FTP Server monitor.
The TCP Port monitor connects to a specified TCP port, and optionally sends a string of data and checks for an output string.
With Samba installed such that a Windows computer can access the remote disk:
- Log File monitoring should work fine.
- The File & Directory monitor will work fine with one big caveat: If you are checking sub-directories there can't be recursive links because the difference between a link and child directory can't be determined from Windows.
- File Age monitor should work fine.

PA Server Monitor downloads and installs quickly, and is easy to configure. We suggest trying the fully-functional 30-day trial to see how it works in your environment.
