Default Parameters for RedisStatsTest

The RedisStatsTest presents to you a plethora of useful metrics on the performance of the Redis server, and quickly points you to the problem areas. With the help of these metrics, you can figure out:

• Are there more keyspace misses than hits? If so, what could be causing them - expired keys? or evicted keys?

• Are too many connections contending for the server's resources?

• Were any connections rejected?

• Is the network throughput of the server optimal?

• Are more full synchronizations happening than partial ones?

• Are partial synchronizations failing?

This page depicts the default parameters that need to be configured for the RedisStatsTest.

• The TEST PERIOD list box helps the user to choose how often should the test be executed.

• 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.

• Once the above values are provided, click on the UPDATE button to register the changes made.

When changing default configurations of tests, the values with “$” indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to “xyz” and $port will be changed to “80” when configuring a test.
