missing OSD hosts specific data

Hi,
Why I do not get any hosts data ( like IOPS,latency, Network ...etc )?

Any help/troubleshooting tips will be appreciated ?

node_exported seems to be up and running and I am getting cluster data

Start by reproducing the reported response from the node_exporter endpoint at 127.0.0.1:9100/metrics and compare its general node metrics with the missing OSD-specific data. Then inspect the collectd integration and its configuration or logs to determine where OSD metrics stop being collected. No file or test is named, and done would require identifying the cause and documenting or implementing a verified resolution.
