Polling Objects Data Collection

AlliedView NMS Administration Guide (Setting Up Performance Management)
After filling in these fields for an Identifier, click Apply and it will be added to the Data Identifier List. Once added, you can
click Modify to modify the Identifier or Remove to remove it.
Once all the Identifiers have been configured, click Apply. This adds the Polling Object to the database and the statistic to
the Configured Collection Panel.
8.3.2.2 Modify a Polling Object
Once set up, modifying the Polling Object will be necessary when you:
• Stop data collection for all the associated Polled Data
• Modify the properties of existing Data Identifiers
• Add new Data Identifiers to add to the Polled Data
To modify a Polling Object, select Edit -> Polling Objects, and then perform these steps:
1. Select the polling object from the left panel, and then select the Modify radio button just below the list.
2. Under Polling Properties, change the Active and Update Managed Objects checkboxes, if desired.
Note: The information under Device Match Criteria is not editable.
Save Col-
lected
Data
If unchecked, specifies data will not be stored, and can be viewed only by the Real Time monitoring using
Current StatisticGraph you do not want to store the collected data, “uncheck” this check box. Default:
True (Checked).
Save
Absolute
This option is applicable only for Counter type OIDs. By default, data collected for Counter type OIDs is
not stored as it is. The difference between the previous data and latest data is collected and stored. If the
exact value (absolute value) of collected data has to be stored for Counter type OIDs then this check box
should be checked.Data collected for OIDs of other data types are saved as absolute values. Default:
False.
Time
Average
If you check this checkbox then the Time Average will be calculated as (Latest collected value + Previous
value) / Difference in Data collection Time value.This is mostly calculated for Counter type and Gauge
type Data identifiers where the data collected will be an incremental value and at one point will reach the
final value and reset to Zero. As this reset may happen soon and very often, it is preferred that a Delta
value is derived from two consecutive Polls. Default: false.
Use
Threshold
Check to apply threshold for this Identifier. Default: False (unchecked).
Thresh-
old List
A list of thresholds to apply to this data. Click the ellipses (...) to get a pop-up list of applicable thresholds.
Select the desired thresholds from the pop-up list (Shift+click to select multiple thresholds), and then click
OK in the pop-up window.
Failure
Threshold
Number of consecutive failures after which the threshold event should be generated. This can be used
where a single Poll (Datacollection for the Data identifier) is not stable. For example, assume the Data
identifier has a threshold associated and it is predicted that the data collected can be crosschecked 3 times.
If the collected value still exceeds the Threshold value then it means that the collected data is stable and
this may result in Performance degradation. Default: 1.
Log
Directly
This option allows the polled data to be saved directly to a text file (comma-separated). The text file will
be located in the NMS Server installation directory on the NMS host machine and will be named <device
name or IP address>_<polled data name>.txt (e.g. 172.16.33.2_ifInOctets.txt).
Note: This option is useful for quickly viewing the raw values as they are collected
form polling but should not be used for long term data collection to avoid filling
up the NMS server disk storage.
