Prometheus Pushgateway Timestamp Error

[subin8848]

The dump file has correctly collected the data. But, while trying to push the metrics to Prometheus using Push Gateway, Prometheus is not populated with data but with push_time_seconds as 0 and push_failure_time_seconds with large values (Example: 1.5932354227576308e+09).

The Prometheus Pushgateway log collects the following error message:

msg="pushed metrics are invalid or inconsistent with existing metrics" method=POST source=10.244.0.0:17937 err="pushed metrics must not have timestamps"

I guess timestamp has to be removed before pushing it to Prometheus Pushgateway but not sure.

Additionally, I am getting the following error in the Pipeline log:

ERRO[2020-06-27 11:45:11.307455] http reply error="unexpected status code 400 while pushing to http://10.13.92.229:9091/metrics/job/telemetry/instance/pipeline1_18391200352046182925" instance=pipeline1 jobName=telemetry pushGWAddress="http://10.13.92.229:9091" pushURL="http://10.13.92.229:9091/metrics/job/telemetry/instance/pipeline1" tag=pipeline

I am stuck in this problem, please help me to get out of it.
