<p>Redis and Argus work together to provide all-round performance monitoring. You can view the resource usage information about Redis through Argus. The following table describes the commonly used metrics.</p> <table border="1" cellpadding="0" cellspacing="0"> <tbody> <tr> <td style="background-color:#ededed; vertical-align:top"> <p><strong>Metric</strong></p> </td> <td style="background-color:#ededed; vertical-align:top"> <p><strong>Name</strong></p> </td> <td style="background-color:#ededed; vertical-align:top"> <p><strong>Description</strong></p> </td> </tr> <tr> <td style="vertical-align:top"> <p>redis_cluster_connected_clients</p> </td> <td style="vertical-align:top"> <p>Connection usage</p> </td> <td style="vertical-align:top"> <p>Ratio of the current connections to the maximum connections, in percentage.</p> </td> </tr> <tr> <td style="vertical-align:top"> <p>redis_cluster_instantaneous_input_kbps</p> </td> <td style="vertical-align:top"> <p>Inbound network traffic</p> </td> <td style="vertical-align:top"> <p>Total inbound traffic per second on the network port of the master Redis instance, in KB.</p> </td> </tr> <tr> <td> <p>redis_cluster_instantaneous_ops_per_sec</p> </td> <td> <p>ops</p> </td> <td style="vertical-align:top"> <p>Times of command executions per second by the user.</p> </td> </tr> <tr> <td> <p>redis_cluster_instantaneous_output_kbps</p> </td> <td> <p>Outbound network traffic</p> </td> <td style="vertical-align:top"> <p>Total outbound traffic per second on the network port of the master Redis instance, in KB.</p> </td> </tr> <tr> <td> <p>redis_cluster_mem_fragmentation_ratio</p> </td> <td> <p>Memory fragmentation ratio</p> </td> <td style="vertical-align:top"> <p>Fragmentation ratio of memory, in percentage.</p> </td> </tr> <tr> <td> <p>redis_cluster_response_time</p> </td> <td> <p>Response time</p> </td> <td style="vertical-align:top"> <p>Connection response time of the master Redis instance, in milliseconds.</p> </td> </tr> <tr> <td> <p>redis_cluster_status</p> </td> <td> <p>Redis monitoring status</p> </td> <td style="vertical-align:top"> <p>Monitoring status of the master Redis instance.
