When your NetScaler appliances are running in a High Availability (HA) pair you should be aware when failovers occur, as this indicates an issue on one or both of the appliances, which you need to solve before both the appliances have the same issue. In the case the latter happens, or is already the case, the appliances will fail over continuously, which is known as HA failover ‘flip-flopping’.
Are you aware when an administrator has forgotten to save configuration on a Citrix NetScaler device? If configuration is not saved after a configuration change it will get lost when the NetScaler appliance restarts. This can obviously have severe consequences. MetrixInsight for NetScaler will alarm you whenever unsaved configuration is detected.
Certificates have a limited validity time and need to be renewed once in a while. Expired certificates may impact the availability of services. MetrixInsight for NetScaler monitors the expiration state of NetScaler certificates and alarms you when they are going to expire and have been expired.
In this article, we present an overview of cluster monitoring using Rancher and Prometheus as well as provide some brief setup tutorials for both tools. We further introduce a metric visualization tool called Grafana that transforms your Prometheus time-series data into graphs and visualizations. MetricFire specializes in monitoring systems. You can use this product with minimal configuration to gain in-depth insight into your environment.
In this article, we are going to look at how to monitor Redis performance using Prometheus. This will allow Redis Administrators to centrally manage all of their Redis clusters without setting up any additional infrastructure for monitoring. To follow the steps in this blog, sign up for the MetricFire free trial, where you can use Graphite and Grafana directly on our platform.
Web servers are among the most important components in modern IT infrastructures. They host the websites, web services, and web applications that we use on a daily basis. Social networking, media streaming, software as a service (SaaS), and other activities wouldn’t be possible without the use of web servers. And with the advent of cloud computing and the movement of more services online, web servers and their monitoring are only becoming more important.
