High memory usage-f5-all
Vendor: f5
OS: all
Description:
Indeni will alert if the memory utilization of a device is above a high threshold. If the device has multiple memory elements, each will be inspected separately and alert for.
Remediation Steps:
Determine the cause for the high memory usage of the listed elements.
How does this work?
This script uses the F5 REST API to retrieve the current memory usage of each TMM core.
Why is this important?
The various memory components of an F5 unit are important to track to ensure a smooth operation. This particlar metric focuses on the memory usage per TMM core.
Without Indeni how would you find this?
These memory metrics are available through SNMP, TMSH and the web user interface under Statistics/Performance.

memory-usage:
why: |

can-with-snmp: true
can-with-syslog: false
cpu-usage:
why: |
Tracking the CPU utilization of all processing cores on an F5 unit is critical to ensure capacity isn't reached. Should capacity be reached on data plane cores, new connections and sessions may fail to be processed. This particular alert focuses on the cpu usage per TMM core.
how: |
This alert uses the F5 iControl REST API to retrieve the current CPU usage of all TMM cores.
can-with-snmp: true
can-with-syslog: false
memory-total-kbytes:
why: |
Tracking total memory on the system is critical to evaluate and assess current memory utilizatiion.
how: |
This alert uses the F5 iControl REST API to retrieve the total memory on the system.
can-with-snmp: true
can-with-syslog: false
memory-free-kbytes:
why: |
Tracking free memory on the system is critical to evaluate memory utilization and identify possible memory leaks.
how: |
This alert uses the F5 iControl REST API to retrieve the free memory on the system.
