Monitor Cluster Connectivity

A cluster should be in a stable form to perform optimally and give maximum output. Partially connected scenarios call for immediate handling. NCache provides the following methods to keep a check on cluster connectivity:

  • NCache Monitor
  • Email Alerts
  • Event Viewer
Note

Cluster connectivity for different store types can be monitored by following the same steps as listed below.

Prerequisites

  • Please ensure that the time on your server machine and the machine where the NCache Management Center runs is synchronized with the World Clock Time.
  • Ensure the NCache Service is started. If not, proceed with the following:

In the command line tool of your choice, enter the following command (run as admin):

Start-Service -Name NCacheSvc

For .NET Core, make sure that you run the NCache Service as an administrator. Here are the steps to do so:

  • Open the Services window and look for NCache in the list.
  • Right-click on NCacheSvc from the list and choose Properties.
  • Go to the Log On tab and click on the Browse button.
  • In the object name field, type Administrator and click on the Check Names button.
  • It will pick the appropriate Administrator, then click OK.
  • Now, set a Password and click OK.
  • Right-click on the NCacheSvc and choose the Restart option. Now your service will start running as an administrator.

Using the NCache Management Center

  • Launch the NCache Management Center by browsing to http://localhost:8251 or <server-ip>:8251 on Windows and Linux.

  • In the left navigation bar, click on the Clustered Caches or Local Caches, based on your requirement.
