The new Data Collection Manager feature in OpManager aids in viewing all monitor/interface/credential related issues in a single pane, so that any monitors/interfaces without ongoing data collection can be easily identified.
From the performance aspect, DCM also lets you improve the efficiency of polling and reduce unnecessary polling load on the server. It improves the overall data collection performance in the OpManager server and helps streamline the server's resources to reduce unnecessary load.
To access the Data Collection Manager, users can go to Support → Diagnostics → Data Collection Manager. and enable it.
DCM basically monitors issues in data collection based on three criteria:
The functionality of Data Collection Manager can be summarised as follows:
Once enabled, DCM constantly monitors the polling activity of each monitor/interface/credential in OpManager.
If the data collection of a monitor continuously fails for 6 hours or more, it is moved to a 'Delayed Polling' state in DCM. Note that 6 hours is the default value, and the user can configure this value to be anywhere between 3-12 hours.
In the Delayed Polling state, the polling interval of the monitor is increased to 6 hours irrespective of the interval already provided in the monitor. The user can configure this interval to be anywhere between 3-12 hours.
During this Delayed Polling state, if the data collection resumes for the monitor, it will be moved back to the normal state.
On the other hand, if the monitor doesn't resume data collection for a period of 7 days in Delayed Polling state, it will be moved to 'Disabled' state and no polling will happen for that monitor from that point of time. This value can also be configured to be anything between 3-7 days.
The details about these failed monitors/interfaces/credentials can be sent as reports to the user on a daily basis. Details to be sent and all other settings related to DCM can be configured under the Settings tab in the Diagnostics page.
The DCM Settings screen consists of the following fields that can be configured by the users:
The active credential profiles of every device are tested once every 24 hours. This is to ensure data collection issues do not arise because of incorrect/invalid credentials. If there are credentials of multiple protocols (SNMP, WMI, CLI and so on) for the same device, all the profiles are tested and only the profiles with issues are displayed in the Diagnostics page. Data collection based on all other protocols is carried on as usual.
This is an automated action in OpManager, but you can also manually test a failed credential by clicking on the "Test Credential" button next to the failed credential of your choice from Support → Diagnostics → Failed Credentials page.
A dedicated Audit page is also available for the Data Collection Manager module, under Settings → Reports → Audit → Data Collection. All events regarding data collection management and diagnostics will be logged under this page, and is available for the user to verify any detail related to data collection in general. This page also has filters to enable the user to filter messages based on Monitor Type/Period/Devices.
