KBI 311774 Issue Addressed: Late Email Alerts Or Missing Data Points On Argent Commander Dashboard And Argent Reports


Argent Advanced Technology 5.1A-1904-C and below


Friday, 23 August 2019


For systems not well tuned — especially in a large installation with more than 1,000 servers — users may find data points are missing on Argent Commander Dashboard or Argent Reports

Another symptom is alerts emails can be received 30 minutes late

Often the folder ‘PENDING_EVENTS’ contains more than 3,000 files

This issue has been addressed in Argent AT 5.1A-1907-A or later

Technical Background

Folder ‘PENDING_EVENTS’ holds the Work Order files returned by Monitoring Engine processes

The Argent AT Engine must process them in order to save collected Argent Predictor data and fire any Events

Argent AT 5.1A-1904-C or earlier processes the WO files sequentially; both saving Argent Predictor data to database and firing events through Argent Console Engine are heavy I/O functions

The throughput in sequential processing is often poor

As a result, the WO queue can quickly build up when load is heavy

Argent Commander Dashboard and Argent Report rely on saved Argent Predictor data

If WO files are significantly delayed to process, missing data points can be resulted

For the same reason, though Monitoring Engine Process has determined a Rule is broken for a Server/Device, if the WO file is significantly delayed, the alert won’t be fired until it is processed

Argent AT 5.1A-1907-A has been enhanced to address the issue

Internal thread pool is used to process WO files in parallel, which responds well to heavy I/O tasks
