+#. You can set the following resource controls in the cloudstack-agent service:
+
+ - Limit the number of file descriptors
+
+ Default configuration is usually higher, set to lower number explicitly
when required. It is observed
+ that the average FDs for a host with 40 VMs was 380, we can reserve +20%
based on the requirement. Example
+ shown below.
+
+ .. code:: bash
+
+ LimitNOFILE=1500
+
+ - Limit the memory usage
+
+ You can limit the memory usage. For example, set to 2500MB (2500 * 1024 *
1024 bytes) as shown below.
+
+ .. code:: bash
+
+ MemoryMax=2500M
+
+ - Limit the CPU quota
+
+ You can control the CPU allocation. For example,set to allow 2 full cores
worth of CPU time as shown below.
+
+ .. code:: bash
+
+ CPUQuota=200%
+
+#. Reload and restart the cloudstack-agent service after changing any of the
resource controls:
+
+ .. code:: bash
+
+ sudo systemctl daemon-reload
+ sudo systemctl restart cloudstack-agent
