Memcached Uptime Test

In most production environments, it is essential to monitor the uptime of critical cache instances in the infrastructure. By tracking the uptime of each of the cache instances, administrators can determine what percentage of time a cache instance has been up. Comparing this value with service level targets, administrators can determine the most trouble-prone areas of the infrastructure.

In some environments, administrators may schedule periodic reboots of their cache instance. By knowing that a specific cache instance has been up for an unusually long time, an administrator may come to know that the scheduled reboot task is not working on a cache instance.

This Memcached Uptime test monitors the uptime of the target Memcached caching system instance.

Target of the test : Memcached caching system

Agent deploying the test : An internal/remote agent

Outputs of the test : One set of results for Memcached caching system

Configurable parameters for the test
Parameter Description

Test period

How often should the test be executed.

Host

The IP address of the target server that is being monitored.

Port

The port number through which the Memcached caching system communicates.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Is rebooted?

Indicates if the Memcached caching system instance has been rebooted.

 

The values reported by this measure and its numeric equivalents are mentioned in the table below:

Measure Value Numeric Value
No 0
Yes 1

Note:

By default, this measure reports the Measure Values listed in the table above to indicate whether/not the Memcached caching system instance is in rebooted. The graph of this measure however, is represented using the numeric equivalents only i.e., 0 or 1.

Uptime

Indicates the total time the Memcached caching system instance has been up since the last reboot.

Minutes

If the current instance has crossed uptime limit, administrators may need to reboot the server.
