Hi. I'm setting up a prometheus pushgateway to collect metrics.

https://github.com/apache/incubator-uniffle/blob/master/docs/metrics_guide.md#report-metrics-to-prometheus-automatically

rss.metrics.prometheus.pushgateway.addr rss-pushgateway...com:80
rss.metrics.prometheus.pushgateway.jobname rss-shuffle-server
rss.metrics.reporter.class org.apache.uniffle.common.metrics.prometheus.PrometheusPushGatewayMetricReporter

However, I only get the JVM related metrics to show up properly, all the others are collected as zeros.

If I'm setting this up wrong, please correct me. (__)
Your advice will be of great help to me.

I have not see it , and here is our conf and it it very simple:

rss.metrics.reporter.class org.apache.uniffle.common.metrics.prometheus.PrometheusPushGatewayMetricReporter
rss.metrics.prometheus.pushgateway.addr   <normal_ip>:9091
**rss.metrics.prometheus.pushgateway.report.interval.seconds 20**
rss.metrics.prometheus.pushgateway.jobname  <normal_jobname>

How about add this:
rss.metrics.prometheus.pushgateway.report.interval.seconds

Hi,

I am seeing a similar issue where I see most of the metrics show a value of 0.
Any update on this issue?

Could you help share some deployment uniffle version and config options? @BaluDontu . From my deployment, the metric system is valid.

Hi @zuston . I was able to get it resolved. Sorry for the confusion.

I have another question. I am trying to get metric data for these below metrics. I want to understand what is the unit for it?

total_read_data -> Is this in bytes?
total_read_time -> Is this in milliseconds?
total_write_data -> Is this in bytes?
total_write_time -> Is this in milliseconds?
used_buffer_size -> -> Is this in bytes?

Can you point to the documentation about these metrics information?

[zuston]

total_read_data -> Is this in bytes? yes
total_read_time -> Is this in milliseconds? yes
total_write_data -> Is this in bytes? yes
total_write_time -> Is this in milliseconds? yes
used_buffer_size -> -> Is this in bytes? yes

The unit of the metrics about data size are all bytes. @BaluDontu

@zuston How about time metrics ?

[zuston]

@zuston How about time metrics ?

If I'm right, the unit is milliseconds for the time metrics
