Port State Monitoring

The Port State Monitor can be set to automate and manage availability and state of any port at regular intervals to check for its availability and the state. The Port State monitor is very useful in situations where you want to make sure a port is available 24x7. The automated Port State Monitor is a simple yet highly effective tool in achieving this. It saves you the time you would take to manually determine the status of a port as well as provide you with a report showing the history of its availability. AppPerfect's Port State Monitoring is the ideal solution to monitor the port for availability and state. Port State Monitoring with AppPerfect is extremely lightweight and adds negligible overhead to target system while monitoring.

This tutorial provides a brief introduction on Port State Monitoring using AgentlessMonitor.

Configuring Agentless Monitor for Port State Monitoring

Following steps will explain how you can configure AppPerfect for Port State Monitoring :

1. Once you are logged into the Monitor Server you can see the Web-UI from which you can access all the features of the Monitor Server. Click the Monitors link from the top navigation bar. This will take you to Monitors tab. Click on Add button to Add a New Port State Monitor.
2. Next Step is to define the Port State Monitor. Provide the IP Address or Host Name of the target machine/router whose availability needs to be monitored.
3. Select the Port State Monitor Type from the drop down. AppPerfect supports monitoring for machines, routers, ports etc. Select the monitor type as Port State for Port State Monitoring.
4. Specify a meaningful identifier for the monitor which will help identify the monitor in future. AppPerfect also supports legacy agent-based architecture. In case you need to use agent-based monitoring, AppPerfect can provide agent for monitoring remote machine, in which case it requires the agent to be deployed on remote machine running at a specific port.
5. Specify the Data Fetch Interval which represents the time interval for which application should wait before fetching the monitoring data from the device. Monitoring Data will be fetched after every specified fetch interval. The smaller the time interval, the more granular the data. However, smaller time intervals also result in a much larger data set.
6. You can specify if the monitor should be Active as soon as its added or should it be in suspended state. You can also specify if all the attributes should be monitored or only some predefined attributes should be monitored.
7. Next Option is to provide port number you need to monitor and time out. Once you are done providing the details, click on Validate Connection button to confirm that monitored device is accessible.
8. Next Step is to Select the Attributes to monitor. Port State monitoring allows you to monitor the parameters such as state of port and search result. Select the parameters you need to monitor from the list of attributes shown.
9. Next step shows the Attribute details of all the selected attributes in the previous step. You can customize the display labels for each of the attributes here.
10. Next step shows the Attribute Data conversion where you can convert the attribute value to required unit. You can configure the operation which should be performed on the attribute value to create the final output value. F
11. Next step shows the Defining Rules view. This view will provide a list of all numeric attributes. You can select the attributes for which you want to add a rule. A rule is defined as a conditional or threshold value which when exceeds, a notification would be sent. In a typical workflow the monitors extract data from the monitored device and send it to the rules engine. The rules engine evaluates the data to ensure no rule is violated and then sends it to the view manager. However, if a rule is violated, a message is immediately sent to the notification server to alert the user about the rule violation.Rules can be defined at a later stage as well. For details on how you can add/edit rules for the monitor, please see the Rules chapter.
12. Next step shows the Security & Notification settings. When a rule is violated a notification is sent out to all the concerned users that a particular event has occurred and needs to be dealt with. This process is called notification. AppPerfect provides five modes of notification. They are Email notification, SMS notification, Custom notification, Log notification, Database notification, SNMP Trap notification. For details on each of the supported notification , please see the Notification chapter. In this view you can configure the type of notification which should be sent on Rule violation, Users/Groups to whom notification should be sent and also the subject and details on the notification message.
13. Click on finish button. We are done adding the monitor for Port State Monitoring. Now go to Status tab on left sidebar. Expand the data for IP provided in IP Address while creating the monitor. Expand the Port State monitor. Click on + icon against the charts that you want to monitor in your Dashboard and you can view the detailed results for each of the attributes being monitored for the target device.
