How to use Excel to analyze K2 Hostserver debug logs


Every now and then, you need to look at K2 Hostserver log and you wish if there is a better way to filter the log file. Fear no more! You can now use Excel to analyze the K2 logs.



K2 HostServer logs are written to the [Program Files]\K2\Host Server\Bin folder by default. The default file name is HostServer.log with the timestamp and cycle number appended to the name.


1. Rename the file to have a 'csv' extension e.g. change 'HostServer210526_1.log' to be 'HostServer210526_1.csv'.

2. Open the file in Excel.
3. Right click Column B (by right-clicking the column name) which contains the datetime of the log entry and select Format Cells.

6. Expand Column B to fit the contents.
7. Hide columns I - M by right-clicking and selecting Hide from the context menu.
8. Click on the Select All button (above Row 1 and to the left of Column A).

9. Select the Data tab (top of the screen in Excel) and click on Filter.

Now you have the ability to hide rows by filtering out redundant information depending on what the issue is. If you want to save the file and keep the Excel formatting, then you have to save it as an .xlsx file.
