Server Dashboard

Dashboard provides different types of views for monitoring various counters. Views are specific to the counters. After selection of a cluster in NCache Monitor, you can either use default dashboard for monitoring performance, health or events of cache cluster or you can define your own dashboard according to your needs. Server Dashboard is one of the default dashboards which appears automatically after the selection of a cluster. Server dashboard cannot be modified, however you can retrieve server dashboard any time from View option. Server dashboard contains following graphs:
You can view the cluster Dashboard from the following option:
Cluster Health
Cluster health shows the connection status among the nodes of a cluster. It displays information in a form of list having following values:
  • Status: It shows the status of every node in a cluster i.e. running, stopped, state transfer etc
  • Node: Nodes IP addresses are shown in this column.
  • Connection Status: It shows connection status of all the nodes with other nodes in a cluster. A node can either be fully connected (connected to all nodes in a cluster) or partially connected (connected to some of the nodes in a cluster).
  • Broken Link: It shows the broken links of a corresponding node with the other nodes in case of partial connection.
  • Clients: It shows the number of clients connected to the corresponding node.
NCache CPU Graph
NCache CPU graph shows CPU cycles consumed by NCache Server.
NCache Network Graph
NCache Network Graph contains two counters:
  • Current Bandwidth: It is an estimate of the current bandwidth of network interface in bits per second (BPS). For interfaces that do not vary in bandwidth or for those where no accurate estimation can be made, this value is the nominal bandwidth.
  • Bytes Total/sec: It is the rate at which bytes are sent and received over each network adapter, including framing characters. Network Interface/Bytes Received/sec is a sum of Network Interface/Bytes Received/sec and Network Interface/Bytes Sent/sec.
Cache Size Graph
Cache Size graph shows cache data against the total capacity of the cache.
NCache Request/sec Graph
Number of requests received (meaning cache commands like add, get, insert, remove etc.) from all clients by this cache server.
NCache Memory Graph
Private Bytes is current size of the memory in bytes that shows this process has allocated and cannot be shared with other processes.
Events Logs
Here you can monitor events of all registered sources. Source can be any software that logged the event, which can be either an application name such as NCache, or a component of the system or a large application such as ASP.NET. Event log service records all the events in the Application logs. The Application log contains events logged by applications or programs. For example, a database program might record a file error in the Application log. The program developer decides which events to record.
Event Viewer : A component you can use to view and manage event logs.
Any event of a registered source fired will be shown with respect to the node in Event Logs view. It contains the following values:
  • Type: Type/category of the event which is logged by the registered source, that is: Information, Error or Warning.
  • Node: IP of the node that has fired this event.
  • Date: Date at which the event is logged on a corresponding node.
  • Time: Time of the event.
  • Source: Source which generates the event, this can be any source which are registered in Event log.
  • Message: Actual message of the event. You can add number of sources in Event Log to monitor activities on that source.
