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
- Please make sure that the time of your server machine and the machine where NCache Web Mnager is running is synced with the World Clock Time.
- Make sure NCache Service is started. If it is not started, do the following:
In PowerShell, enter the following command:
Start-Service -Name NCacheSvc
For .NET Core, make sure that you run NCache service as an administrator. Here are the steps to do so:
- Open 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 NCache service and choose the Restart option. Now your service will start running as administrator.
NCache Web Monitor
Launch NCache Web Manager by browsing to http://localhost:8251 (Windows) or
<server-ip>:8251(Windows + Linux).
In the left navigation bar, click on the Clustered Caches or Local Caches, based on your requirement.
- Click on the "..." button on the right corner against the cache name and click on Monitor Cluster. Make sure that the cache is already running.
- In the new tab, a new browser window will pop open showing the Server Dashboard with the Cluster Health tab.
- The image shows the cluster connectivity of a two node cluster which is fully connected.
NCache provides another option for monitoring as email alerts. Email alerts can be configured through NCache Web Manager. Whenever a split-brain (partial connectivity) occurs, the user is emailed an NCache alert based on the email address configured.
