I've been trying to use Adam's nmonmerge.sh script to combine multiple .nmon files from multiple days (I have a .nmon generated every 24 hours) and I'm getting "Data column(s) for axis #0 cannot be of type string" error:

And also tried the merged file generated when using nmon analyser v66.xlsm (not the final .xls file but the file_first_to_file_last.nmon file it generates when using the Merge = YES option) and got "b.getTimezoneOffset is not a function" error:

Both merged files were succesfully parsed with NMONVisualizer_2021-04-04.jar so I guess they are ok and the issue is with nmonchart.

Why I don't use those tools? Because I like nmonchart better.

Hi,

I'm using nmonchart via a hourly cronjob which executes:
/usr/local/bin/nmonchart.cron; service nmon restart >/dev/null 2>&1; sleep 1m; rsync -arz -v --delete -o -p /var/log/nmon/ /shared/sys/nmondata/uname -n/ >/dev/null 2>&1

Occasionally I got errors for the rest of the day:
sed: couldn't open file /tmp/nmonchart.sed.15901*: No such file or directory
rm: cannot remove `/tmp/nmonchart.sed.15901*': No such file or directory

Please help and fix it.

Thanks a lot in advance
Thomas

Suggestion, in nmonchart, change the shebang line from
#!/usr/bin/ksh
to
##!/usr/bin/env ksh

This lets the script run on systems like Macs that have the shell in a different location.

I would have made the change myself, but I cannot seem to crate a branch in the repo
