CentOS 7 - SysStat 10.1.5-19.el7 : nothing in some graph

[Tirguy]

Hello,

My configuration :

• Linux CentOS 7.9.2009
• SysStat version 10.1.5-19.el7
• KSar last version on Linux Ubuntu 20.4 (Java 11)

Sysstat takes a new measurement every minute and generates a new sarXX file every day at 23:59

When i want to load in KSar the sar file, nothing appears... or almost !!!

I do not have anything on the CPU graph, Device Block graph, Interface Error and trafic graph, Process graph, Swap graph... Whereas it seems to have a graph for Kernel VFS, Load, Sockets graph (NB: KMem graph just make appear the memory evolution, but du not graph anything on the cache/buffer/active/dirty graph).

Here is the beginning of the SAR file :

Does some people have this problem too ?

With an old KSar version (https://github.com/ppalucha/ksar2) i have this screen :

Whereas with this version, i have this screen :

Is it an issue ?

Thank's for help,

Please provide such a file.

when you refer to latest kSar version, do you mean the latest snapshot version?

[Tirguy]

I mean "the last release" ;-) Not the last snapshot because i do not have something to make it :-(

Do you really want all the file ?

[Tirguy]

prjpgsa001_sa03.sar.zip

Here is an exemple....

[Pitterling]

Your file format and content is in french. That is not expected by kSar.

• your decimal separator is a comma instead of point
• your "Average" lines are also translated

Seems like you adjusted how SAR data is collected. All errors should be shown by the ksar_all.log file. Do you have such a file?

Snapshot versions are also provided on the Release page. But the last available is also 2y old and does not contain all changes afterwards.

I compiled a version which is handling your french version as well .. give it a try and provide feedback. Furthermore it seems your example file is not complete as it does not contain the last lines (Summary/Resume). Maybe you can provide such a file again to check if these lines are also handled correctly.

@Tirguy Any feedback to my last comment?

[Tirguy]

Sorry... was sick and in bed since 2 weeks :-(

Unfortunately, I don't have control over the way sar files are built on our servers: it's a separate team that manages that... Indeed, the file is in a "French" format.

I compiled a version which is handling your french version as well : thank's ;-)

Apparently, this version seems to handle correctly the import of this type of file... everything seems to be back in order :-D

Here is the ksar_all.log file that was generated by this special version. ksar_all.log

The example file is not complete as it does not contain the last lines What should I find in this file? What are the last lines I should find?

[Pitterling]

The last lines in a sar file are the summary lines. In french it would be "Résumé:"

Would be great to get a sar file with "Moyenne " and ""Résumé:"

Thanks

[Tirguy]

It's strange... I've search an example in all computer from my dev' plateform, i just have "Moyenne" ("average" in english) at the end of file. Here is 3 differents files from different server on my dev' plateform :

• CentOS 6.4
• Centos 7.9
• Rocky8

Not sur that there is many activity on them ;-)

cause you are not collecting all statistics. For your stats only Average will be appended. "FILESYSTEM" stats and a few others hat "Summary" instead of "Average"
