Hey there,
we just configured the server monitoring on our FreeBSD server. But the agent reports there is a memory usage of always above 85%. We have 8 GB of RAM / memory installed on the server. Right now we are using Zabbix also on the server. Zabbix shows us a usage of roughly < 50% of the memory. Why is there such a big difference? Why is Site24x7 reporting such a high usage? The command "top" on our server shows us right now the data like this "Mem: 1098M Active, 4204M Inact, 2189M Wired, 4376K Cache, 828M Buf, 456M Free" There you can see that 4204M is inactive and 456M is free. Zabbix adds the inactive memory to the free memory, while Site24x7 only takes the free memory, which is causing the alerts. Any solutions?
We wanted to write this to support, but everytime we are sending the message an error occurs.

Hi Schroeder,
Our FreeBSD server monitoring agent uses "sysctl -n hw.physmem" and "vmstat -H" commands to get information about the total and free memory values. Memory utilization is calculated based on the output of the above commands. Hence, there is a difference in Memory utilization values between Site24x7 and the top command/Zabbix.
We are analyzing the possibility of implementing the top command output to fetch the memory utilization information from FreeBSD servers. I will update further on this post after our analysis.

Hi Schroeder,
We have included some changes in the script file that is used for data collection to use top command for fetching the memory utilization information. We request you to perform the below steps and update us with the status:
i) Stop the Site24x7 Server monitoring agent using the below command:
/etc/rc.d/site24x7monagent stop
ii) Please go to /opt/site24x7/monagent/scripts directory and rename the script.sh file to script_old.txt
iii) Download the attached script.zip file and extract it for the new script.sh file. Please copy the script.sh file to /opt/site24x7/monagent/scripts directory
iv) Start the Server monitoring agent using the below command:
/etc/rc.d/site24x7monagent start
Let the Server monitoring agent run for some 30 minutes and check the memory utilization values fetched. Please let us know if the Memory Utilization is shown as expected.
