## Data Collection

Using this option, Performance Data collection can be scheduled for the given number of polls. Except for the availability check and health, other performance parameters, like memory usage data, can be collected at the scheduled number of polls. This would be helpful in decreasing the load on the system of the users who want to monitor availability and health alone.

For example, if the polling interval of a particular server monitor is one minute and the performance data is scheduled to be collected once every five pollings, the availability of the server is checked every minute, whereas the performance data, like CPU Memory, is collected every five minutes.

## Servers

Under the Server tab, select the monitor type and the metric name that you want to enable/disable from the respective drop-down menus. You can configure the polling status by:

**Monitor Type** – This will be the default polling status for any new monitor added. All monitors of this type will have the default polling status unless specific customization is applied to individual monitors.

**Monitors** – Use this option to change the polling status of any particular monitor(s).

**Note:**

- Changing the polling status or data collection settings for a Monitor Type will override any customizations made at the individual monitor level.
- When multiple monitors are selected, the Monitor Type configuration value will be displayed to avoid confusion.
- While selecting a single monitor, displaying the individual value for a monitor can result in losing behavior uniformity. To avoid that, the Monitor type configuration value is displayed.
- In this context, **Configure Data Collection Settings** and **Configure Data Collection Interval** behaviours are being discussed.

### Disk I/O Statistics Monitoring

Using this option, Disk IO Stats can be disabled to never collect data, collect data at every poll, or collect data at customized intervals for the servers. On enabling the option, Data Collection will happen for Disk IO stats, and you can see the details of Disk IO Stats in the Server details page. If it is not enabled, Data Collection will be stopped for Disk IO Stats.

**Supported Server Monitors:** AIX, Linux, Sun Solaris (SSH/Telnet), Windows.

**Data Collection Settings:**

- **Delete entry if it is not discovered for "3" consecutive polls:** This option allows you to remove the disk I/O from Applications Manager if it is not detected during data collection. You can specify the number of consecutive polls after which the system will delete the disk I/O if it remains undiscovered.

### Disk Monitoring

The Disk Monitoring option can be disabled to never collect data, collect data at every poll, or collect data at customized intervals for monitoring of Local Disk. By default, Local Disk monitoring is enabled for all Windows servers.

**Supported Server Monitors:** AIX, FreeBSD, HP, Linux, MAC OS, Novell, Sun Solaris (SSH/Telnet), Windows.

**Data Collection Settings:**

- Network Mapped Drives and Volume Mount Points are supported only for Windows Monitors. Learn more about [WMI-related limitations in Network Mapped drives](https://pitstop.manageengine.com/portal/en/kb/articles/limitation-in-monitoring-network-drives-via-wmi-in-windows-monitors).
- **Delete entry if it is not discovered "3" consecutive polls:** You can delete the disk from Applications Manager if it is not discovered in the data collection. Configure the number of polls after which the disk will be deleted.
- **Ignore specified Components:** Configure Applications Manager to ignore data collection for specific disks by entering their names, separated by commas. All disks that start with the specified disk name will be ignored from monitoring. For example, specifying `/run` will exclude `/run/101`, `/run/102`, and `/run/103`.

**Note:** Details associated with Windows Network Mapped drives and Windows Volume Mount Points will not be collected in SNMP mode.

### Memory Utilization

Use this option to disable data collection (never collect data), collect data at every poll, or collect data at customized intervals for monitoring memory utilization.

**Supported Server Monitor:** Linux

**Data Collection Settings:**

- **Skip buffer and cache from monitoring:** Exclude monitoring for specific servers based on monitor type or monitor level.

**Note:**

Each monitor type allows enabling/disabling metrics, configuring polling status at Monitor Type or Monitor level, and in many cases specifying custom intervals or deletion rules when metrics are not discovered for a configured number of consecutive polls.

**Note:** Changing the polling status of the Monitor Type will override customizations done at the monitor level. The customized time interval must be greater than or equal to the monitor polling interval.
