Redis Uptime Test

Use this test to promptly detect unscheduled reboots and unexpected breaks in the availability of the Redis server.

Target of the test :A Redis server

Agent deploying the test : An internal agent (recommended)

Outputs of the test : One set of results for the target Redis server

Configurable parameters for the test
Parameters Description

Test period

How often should the test be executed

Host

The host for which the test is to be configured.

Port

The port at which the specified HOST listens.

Redis Password and Confirm Password

In some high security environments, a password may have been set for the Redis server, so as to protect it from unauthorized accesses/abuse. If such a password has been set for the monitored Redis server, then specify that password against REDIS PASSWORD. Then, confirm the password by retyping it against CONFIRM PASSWORD.

If the Redis server is not password protected, then do not disturb the default setting of this parameter.

To determine whether/not the target Redis server is password-protected, do the following:

  • Login to the system hosting the Redis server.

  • Open the redis.conf file in the <REDIS_INSTALL_DIR>.

  • Look for the requirepass parameter in the file.

  • If this parameter exists, and is not preceded by a # (hash) symbol, it means that password protection is enabled for the Redis server. In this case, the string that follows the requirepass parameter is the password of the Redis server. For instance, say that the requirepass specification reads as follows:

    requirepass red1spr0

    According to this specification, the Redis server is protected using the password red1spr0. In this case therefore, you need to specify red1spr0 against REDIS PASSWORD.

  • On the other hand, if the requirepass parameter is prefixed by the # (hash) symbol as shown below, it means password protection is disabled.

    # requirepass red1spr0

    In this case, leave the REDIS PASSWORD parameter with its default setting.

Measurements made by the test
Measurement Description Measurement Unit Interpretation

Total uptime of the Redis server

Indicates the total uptime of the server.

Minutes

A low value implies that the server was recently rebooted. From the measure value, you can figure out if the reboot was scheduled or unscheduled.

A high value could indicate that a scheduled reboot has failed.

Is under maintenance?

Indicates whether the database instance is under maintenance or not.

 

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

Measure Value Numeric Value
Yes 1
No 0

Note:

This measure reports the Measure Values listed in the table above to indicate whether the target database instance is under maintenance. However, in the graph, this measure is indicated using the Numeric Values listed in the table above.
