Minio Service Uptime & Minio Server Uptime aren't different #8

Open abhinav-chittora opened 6 years ago

abhinav-chittora commented 6 years ago

Currently, minio_server_uptime metrics show minio_uptime data. However, there are chances, that service uptime (minio_uptime) can be different than server uptime (minio_server_uptime).

https://github.com/joe-pll/minio-exporter/blob/master/minio_exporter.go#L168 issue seems at this line.

Environment: OS Version: Centos 7 MInio Version: 2018-01-18T20:33:21Z

The values are coming from two different data structures of Minio. The minio_uptime comes from ServiceStatus.Uptime, while the minio_server_uptime comes from the ServerInfo structure. I tested on my own and stopped one of the servers. The server uptime is different from the ServiceStatus uptime. If you have one service only these values are the same.

I am using minio on single system and minio_exporter returns the value for service uptime & server uptime. Is there any way to debug outputs?

joe-pll commented 6 years ago

Yes, it is normal to return both values. In the Minio API these values are exposed differently. But in case of a single server are the same. What do you mean with "debug outputs"?

abhinav-chittora commented 6 years ago

The problem is both parameters return the same values however, system uptime and Service uptime are different.

Debug output = verbose mode.
