How It Works

Each Arm - a windows service installed on the server you want to monitor - constantly monitors key performance indicators, such as CPU usage, memory usage, hard drive free space, windows services and windows event log. They report them real-time to Starfish Monitor.

Starfish Monitor is a central windows service that receives this information and generates alarms, if monitored value exceeds specfied threshold.

You can log-in to Starfish Monitor via web browser to examine open alarms and close them. Each alarm generates a notification, that you can receive via email.

Starfish Monitor implements sophisticated alarm comparison mechanism, so you'll get each notification only once and won't be swamped with hundreds emails with almost the same error message.


Download and start monitoring

Download and install Starfish Monitor first, note the server address and thumbprint (shown at the installation end), then download and install Starfish Arm on each server you would like to monitor:


Starfish Monitor requires two open ports:

  • 10888 for http Starfish Monitor Web Portal.
  • 10222 for Starfish Arms to connect to.
Azure endpoints

Installer opens those ports in your firewall, however you need to remember to additionally configure Azure endpoints, if you want to have access from the Internet.

What are those Arms?

In Starfish Monitor, Arm is a windows service running on the machine (server) you want to monitor. Each Arm monitors a single server - the machine on which it is installed.

What if I outgrow my edition and need to upgrade?

You pay the difference and upgrade to the new edition - Please contact our sales team.

What are your payment terms?

We operate on NET-0 payment terms. The order must be paid in full before the license key can be issued. This means that if you are paying by check or bank/wire transfer, it may take a few days to up to a week or more for the payment to arrive and be processed by us before your license key can be issued. If you need your license key in a hurry, you should use the credit card or PayPal payment options.

What does it cost to renew?

To renew the support and maintenance period on your license, the annual renewal fee is 50% of the current retail price for that license. Please note that these prices may be adjusted from time to time.
