I forgot to include the following code snippet from Wim Nelis? script diskstat.pl ? no idea if something has to be adjusted here. This is where he describes and initializes the DS types:

Define the name of each data-set, the unit conversion factor and the RRD type.

Note that RRD requires that the values of type 'DERIVE' are integer. If

however floating point numbers are used, the RRD type must be set to

'DDERIVE'.

my @DS= ( # Define parameters of the datasets [ 'Name' , 1, '' ], # 0 - Name of disk / partition [ 'RdRequest', 1, 'DERIVE' ], # 1 - Read requests [ 'RdMerge' , 1, 'DERIVE' ], # 2 - Read request merges [ 'RdAmount' , 512, 'DERIVE' ], # 3 - Sectors read [ 'RdTime' , 0.001, 'DDERIVE' ], # 4 - Time spent reading [ms] [ 'WrRequest', 1, 'DERIVE' ], # 5 - Write requests [ 'WrMerge' , 1, 'DERIVE' ], # 6 - Write request merges [ 'WrAmount' , 512, 'DERIVE' ], # 7 - Sectors written [ 'WrTime' , 0.001, 'DDERIVE' ], # 8 - Time spent writing [ms] [ 'IoQueue' , 1, 'GAUGE' ], # 9 - Length of I/O queue [ 'IoTime' , 0.001, 'DDERIVE' ], # 10 - Time spent for I/O [ms] [ 'IoWTime' , 0.001, 'DDERIVE' ] # 11 - Time weighted with (9) ) ;

I believe that error is coming out of rrdtool, not perl. Kind regards,

Unfortunately I have migrated our xymon server since then, in addition to that the ?old? linux machine on which diskstat.pl<https://eur03.safelinks.protection.outlook.com/?url=http%3A%2F%2Fdiskstat.pl&data=02%7C01%7Cchristian.becker%40rhein-zeitung.net%7Ceb21615af9c744857b3308d767631885%7C4fed923898bc4f3b96450b99f4d1b669%7C0%7C0%7C637091547631602266&sdata=%2FWH1EjoThac%2BbicAUfDhP7xiKeJkuxJ6GH40wi6Bl58%3D&reserved=0> was initially used doesn?t exist any longer.

Now I wanted to use diskstat.pl<https://eur03.safelinks.protection.outlook.com/?url=http%3A%2F%2Fdiskstat.pl&data=02%7C01%7Cchristian.becker%40rhein-zeitung.net%7Ceb21615af9c744857b3308d767631885%7C4fed923898bc4f3b96450b99f4d1b669%7C0%7C0%7C637091547631612261&sdata=KUvdrGfJz%2FnlW%2BaNyoOvBtvi3cn8kjLPlD8b56N6PAk%3D&reserved=0> again on a new linux client, and therefore I looked to the entry at wiki.xymonton.org<https://eur03.safelinks.protection.outlook.com/?url=http%3A%2F%2Fwiki.xymonton.org&data=02%7C01%7Cchristian.becker%40rhein-zeitung.net%7Ceb21615af9c744857b3308d767631885%7C4fed923898bc4f3b96450b99f4d1b669%7C0%7C0%7C637091547631612261&sdata=GYeGFvcU5l6TvhGL5hSX1P%2BnZmdhLk%2B3Lk40BjG1%2ByI%3D&reserved=0> again, but I found a newer version of diskstat.pl<https://eur03.safelinks.protection.outlook.com/?url=http%3A%2F%2Fdiskstat.pl&data=02%7C01%7Cchristian.becker%40rhein-zeitung.net%7Ceb21615af9c744857b3308d767631885%7C4fed923898bc4f3b96450b99f4d1b669%7C0%7C0%7C637091547631622266&sdata=BGbvfp5EvLYvGLpRCvuxpdqxPMnFxVoQvQMShJx9nak%3D&reserved=0> (now using devmon format).

I followed all the steps, but my result is an entry on the xymon server in the logfile rrd-status.log:

Specify the disks and partitions to be monitored, and the name of the

associated mount-point. The latter is shown in the resulting graph.

require Exporter ;

%Disks= ( "sda1" => { Name => "/boot" }, "dm-1" => { Name => "/" }, "dm-6" => { Name => "/var" }, "dm-7" => { Name => "/opt" }, ) ;

1 ;

My perl isn?t good enough to find out why it says invalid DS type specified. Do you have any suggestions what could have went wrong here??

My xymon client (linuxclient1) is running CentOS 6.6 64 Bit, my xymon server is running CentOS 7.7 64 Bit.

Do you need more information?
