Note

  • All the tests were performed with the default collection interval 2 minutes (Normal).
  • CPU usage is normally ~0.5% with small peaks. If there is a high CPU usage and a long peak, change the collection interval to either 10 minutes (Medium) or 30 minutes (Low).

File size: The log file size that is being monitored.

Number of files: Number of log files that is being monitored at the same time.

Latest/All: File disposition

New content size: The new content that has been written to each log file for each collection interval.

We have tested each scenario separately (only a single scenario has been tested each time). 

For example, consider the scenario 1, here in this scenario we have created a setup of 10,000 log files in the same folder. The setup was configured to monitor the latest files. Each of the log files was of 1 MB.

The collection interval was for 2 minutes. For each collection interval, a new content was added with a size of 1 KB. That is for every 2 minutes; the file size was increased to 1025 KB, similarly, for 4 minutes the file size was 1026 KB and so on.
