Server Monitoring

Server Monitoring

Server Monitoring is a process to monitor server's system resources like CPU Usage, Memory Consumption, I/O, Network, Disk Usage, Process etc. Server Monitoring helps understanding system's resource usage which can help you better your capacity planning and provide a better end-user experience. Your application's health depends on a large part on the health of the underlying server. Server Monitoring ensures that your server machine is capable of hosting your applications. Server Monitoring provides you with data relating to your operating system and when used in conjunction with other monitoring data from the application you get a true glimpse into the working of your system.



Server Monitoring with AppPerfect

AppPerfect offers Server Monitoring solution in the form of AppPerfect Agentless Monitor. AppPerfect's Server Monitoring is the ideal solution to monitor your server's resources. AppPerfect's Server Monitoring is found to be most affordable, cost effective, efficient, reliable and accurate solution by its customers. Regular agents impose a substantial overhead on your server resources in terms of CPU and memory. By contrast, AppPerfect's Server Monitoring solution implements Agentless Architecture and uses existing Operating System services to extract server resource usage information. Server Monitoring with AppPerfect is extremely lightweight and adds negligible overhead to target system while monitoring.

Following steps will explain how you can configure AppPerfect for Server 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 Server Monitor.
  2. Next Step is to define the Server Monitor. Provide the IP Address or Host Name of the target server whose resources needs to be monitored.
  3. Select the Server Monitor Type from the drop down. AppPerfect supports monitoring for Microsoft Windows 2000/XP/2003, Linux x86, Solaris Sparc, Mac OSX and AIX Systems. Select the monitor type which suits your requirement.
    For Windows AppPerfect uses the PDH (Performance Data Helper) library provided by Windows to get system and performance data. For non-windows machine Appperfect supports Telnet, SSH, Rstat protocols to get the performance data.
  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 user credentials and protocol for accessing remote machine. For Windows you need to provide Administrative user credentials. For non-windows machine also select the protocol (Telnet, SSH or Rstat) which should be used to get the monitor data. Once you are done providing the credentials, click on Validate Connection button to confirm that monitored device is accessible.

  8. Next Step is to Select the Attributes to monitor. Server monitoring allows you to monitor crucial parameters such as CPU usage, Memory consumption, Network, Disk usage and Processes that are running on the system. Select the parameters you need to monitor from the list of attributes shown. For details on supported attributes refer to Server Monitor chapter.
    Server Monitoring : Select Attributes
  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 coversion 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. For example by default the Available Physical Memory is in Mega Bytes(MB). In case you need to convert the values to Kilo Bytes (KB), you can set a operator to convert the value from MB to KB. In this case it will be a Multiply operation by 1024.
    Server Monitoring : Attribute Data Conversion
  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 work flow 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.
    Server Monitoring : Defining Rules
  12. Next step shows the Data Management settings. AppPerfect generates vast quantity of data. Effective data management is crucial to ensure a properly functioning monitoring system.When a device is monitored at a regular time interval, AppPerfect requests the device for values of the device properties that it is monitoring. This data is processed and stored by AppPerfect in a database. As the number of monitors defined in the system increase, so does the amount of data. If you have several dozen or hundred monitors, the data can accumulate very quickly. To ensure smooth functioning of the system effective data management is important. In this view, you can set the archiving/purging policies as well as set the frequency with which data should be collected from the monitored devices. For details on Data Management settings, please see the Managing Data chapter.

  13. 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.
    Server Monitoring : Notifications
  14. Click on finish button. We are done adding the monitor for Server Monitoring. You will find the newly added monitor on left hand side Monitor tree. Select the Monitor and on right hand side you can view the detailed results for each of the attributes being monitored for the target device.
    Server Monitoring Results
