I found some server could not get the disk performance information . I checked the load then see this error . Is it because my system kernel version is too high causing exporter not to support the new /proc/diskstats format?
pmm-server 1.13.0

Hello again Fan…
Let me find out from the PMM team if they need a JIRA ticket for this one…

pmm-client 1.17.0 is using node\_exporter that can’t handle changes in the /proc/diskstats format.
The exporter has been updated in pmm2-client.

@Fan ,
Here is a link to the backported patch that fixes the problem in node\_exporter version used in PMM 1.x:
[https://github.com/shatteredsilicon/node\_exporter/commit/cb2dd588eaadf44b53e51a932d44105ea5c14881](https://github.com/shatteredsilicon/node_exporter/commit/cb2dd588eaadf44b53e51a932d44105ea5c14881)
If you are using a RPM based distribution, you can get the .src.rpm to rebuild the binaries here:
