This article outlines the functionality and customization options of the Clients Usage Page on Cisco Meraki networks, providing a comprehensive guide for monitoring and managing client devices
Prometheus has become the de-facto standard for monitoring applications in Kubernetes environments. To monitor Redis with Prometheus, you can use the Redis Exporter. First, you will need to create a user for the exporter in Redis with enough privileges to get stats, allowing it to generate metrics. This is done by using redis cli to run this comman... See full list on sysdig.com #1 Availability The first step to monitor your Redis with Prometheus is the uptime of your server. The metric redis_uptime_in_secondsgives you information on when was the last restart of the server, and an alert on this metric can help you identify unscheduled restarts: #2 Connections usage and errors Lets write a PromQL query to detect rejected connections with the redis_rejected_connections_total metric: Rejected connections can be caused because Redis reached the maximum number of client connections. You can use the redis_connected_clients and redis_config_maxclientsmetrics to calculate the number of available connections in your Redis server: Also, you can create an alert to detect when the usage of network connections is over 85 percent: Want to dig deeper on how to write Prometheus... #3 Latency There are different ways to detect that a Redis server is having high latency issues. One of them is to monitor the redis_slowlog_lengthmetric. The slow queries log, as in other databases, registers the queries that took too long to perform. You can monitor this metric with the following PromQL query: Also, you can calculate the average response time of the Redis server by using the redis_commands_duration_seconds_total and redis_commands_processed_totalmetrics. The following query will alert... See full list on sysdig.com In this article, you learned how to monitor Redis with Prometheus by using an open source exporter. You also learned which Redis top performance metricsyou should look at to ensure the correct functioning of your Redis instances, and to troubleshoot possible issues in your database. Now, you can try out these free Redis monitoring dashboardsfor bot... See full list on sysdig.com Fix Redis ERR max number of clients reached errors by tuning maxclients, improving connection pooling, and identifying connection leaks in your application. In Advanced Settings, select Thresholds & Timeouts, and select Maximum Clients. You can specify a maximum number of client connections that each load balanced server can handle. The NetScaler appliance then opens client connections to a server only until this limit is reached. SIMATIC WinCC Unified Client, Monitor max.

Current server connections are all server connections (Established + TIME_WAIT,etc)
Furthermore, visual representations like the one above help us fully grasp the concept of Monitoring Max Clients.
After taking the advice in the linode library and on this forum, I've lowered my max clients significantly (I've experimented with 12 and 15) and it has successfully kept my server from crashing...
