Subject: prometheus-node-exporter: Metrics scraped from
prometheus-node-exporter are not imported by prometheus
Package: prometheus-node-exporter
X-Debbugs-Cc: [email protected]
Version: 1.9.0-1+b4
Severity: normal
Dear Maintainer,
* What led up to the situation?
Standard prometheus installation - server and clients Debian/trixie
(Raspberry Pi OS/trixie)
* What exactly did you do (or not do) that was effective (or
ineffective)?
Search for the metrics for `node_filesystem_free_bytes` in the prometheus
web interface
* What was the outcome of this action?
The node_filesystem_free_bytes metrics for Debian/Raspios clients do not
appear in
prometheus-db
* What outcome did you expect instead?
If I pass --no-collector.netstat as an argument
(/etc/default/prometheus-node-exporter),
the metrics for node_filesystem_free_bytes is recorded in the database, and
can be
queried.
As a further point, this might indicate what the problem could be ??
I’m using a script that, on a NAT router (OpenWRT), queries the
prometheus-node-exporter
clients via curl and then sends the data to a prometheus-push-gateway, again
via curl.
And there I get the following error message:
# /etc/prometheus-openwrt_nat-scraper.sh
pushed metrics are invalid or inconsistent with existing metrics: 30
error(s) occurred:
* collected metric "node_netstat_TcpExt_SyncookiesSent" {
label:{name:"instance" value:"waals-pi5_prisma_pro_qms"} label:{name:"job"
value:"waals_nat"} untyped:{value:0}} is not a GAUGE
* collected metric "node_netstat_Tcp_InErrs" { label:{name:"instance"
value:"waals-pi5_prisma_pro_qms"} label:{name:"job" value:"waals_nat"}
untyped:{value:0}} is not a GAUGE
[cut cut]
curl: (18) transfer closed with outstanding read data remaining
Maybe this is also the problem with the default setup !?
