Node_exporter: Provide option to ease the update for 0.16.0 release

[SuperQ]

The 0.16.0 release is going to create a large amount of metric name breakage. Let's provide a sample metric_relabel_config so users have the option to duplicate legacy names to allow for smoother dashboard transitions.

[lhoss]

That would be highly helpful indeed 👍
Update: In case there's already work done in this direction, having a pointer to a branch could be useful 👍

ps: I just stumbled on this issue, after I found out that (metric names must have changed since) our existing node exporter dashboards just showed empty charts.

• Extra feature request: if the prometheus team could also offer a small (old->new metric names) mapper/replacer (shell/py) script and/or at least a full (csv)table just containing 2 columns old_name,new_name, so users can easily update their existing configs containing metric names (dashboard jsons, incl. the public ones, alert rules configs, etc).

A final suggestion:

• Documenting such breaking changes (in master) already in https://github.com/prometheus/node_exporter/blob/master/CHANGELOG.md (master branch), before the final release, would help warn people that try out latest/master builds

[beorn7]

I guess I was assigned to this issue as I need to do the relabel config anyway for SoundCloud. However, I'm not familiar with the changes, and it would indeed be a great help if those that changed the metrics could provide a simple old→new mapping as suggested by @lhoss above.

I can produce a diff of the end-to-end output, that should help.

[matthiasr]

does that include all the affected collectors?

[Simonzhaohui]

@SuperQ What's publish plan for release 0.16.0 or 0.15.3 ?

[SuperQ]

The current plan is to publish a release candidate today or tomorrow.

[beorn7]

Foolishly, we didn't take into account that relabeling will only mutate metrics, rather than duplicate them. I cannot really see a straight forward way of creating a smooth transition right now. What you can do is to update node exporters but leave the metrics at their old name via metric relabeling. But eventually you have to migrate so that's not a big help. It just makes the "big bang" migration a bit more atomic (by removing the relabeling).

Non-straight-forward idea:

• Scrape every 0.16 node-exporter twice.
• In the 2nd scrape target, filter out all unchanged metric and relabel the remaining ones according to the table above. Relabel the job name into the same as for the 1st config.

Needless to say, this is expensive and dirty. I think it makes more sense to go for another migration plan. Affected alerting rules are easy to find and can be adjusted to work with both versions. (In most cases, duplicating the alert with each metric name version will do the trick. Aggregation is a bit harder.) For dashboards, going for a big-bang migration might be the most reasonable option.

I'll close this as it doesn't appear to be the way to go. If you have better ideas, feel free to update here or discuss on any of the community channels.

[brian-brazil]

Needless to say, this is expensive and dirty.

It'd also cause issues with up being duplicated.

I still think it might be useful to have metric_relabel_configs, as you can have your dashboards/alerts on the new names while you are still in the process of upgrading your node exporters.

[grobie]

I don't see how metric_relabel_configs help here. Our main requirement is to not break our dashboards for historical data. For that we need to be able to access metrics stored in the old and new format for at least the retention time / one month.

So far I see two main ways to achieve that:

1. Support both old and new names at query time. E.g. update all expressions and add OR operators at the right place. Given we have tens of dashboards and hundreds of expressions, I don't see how to easily achieve that.
2. Store new and old names in Prometheus, and only switch dashboards when new metrics have been collected for long enough. Disadvantages are an increased number of metrics to store for that time frame.

For the second approach, I see two ways:

• add an option to the node_exporter itself, to emit both old and new names.
• provide recording rules and to genereate the old names from the new ones. Problems are staleness (depending on the Prometheus server version) and that timestamps get changed.

[SuperQ]

The recording rules would be my preference. This is the approach I plan to use for GitLab.

[discordianfish]

Just for the record: node_filesystem_* to ..._bytes change isn't in the list above.

[davidbirdsong]

Just to add another annoying scenario. I'm in the process of dragging my org into the 21st century with hopes of moving away from graphite. We've got a blend of 2.6 kernels and 3.4. The 2.6 kernel boxen can't run this latest exporter due to go1.1. I figured I'd run this new exporter version on our 3.4 kernels and eventually drain out all of the 2.6 boxes, but having nodes straddle is pretty unworkable given that no dashboards will work for all nodes in the interim.

I'd be happy to be able to lean on a relabel config just to make the switch once we get our act together and can kill all these ancient kernels.

[SuperQ]

@grobie Do you have any time to add the --include-old-metric-names flag?

[dprittie]

I'm trying to get the new names for these metrics recorded now so we can build up enough history to have a seamless transition.

I know this will be missing the node_filesystem_* to ..._bytes metrics @discordianfish mentioned and possibly more. It would be great if we could get a golden copy of these rules from someone who knows that they are doing.

We now have documentation and an example rules file. Improvements are welcome, but I think this is now covered.

@rfrail3 We intentionally added whitelists for vmstat and netstat to reduce the number of metrics. If you know of any very useful metrics that we dropped from that list, please let us know.

As for the the two network metrics, this was actually a long standing bug, they have been renamed to be correct.

[rfrail3]

That's makes sense, they were a lot of records. In that case, I think that the --help output and the README.md needs to be modified because they still reflects both as enabled, do I need to open a new issue?

  --collector.vmstat        Enable the vmstat collector (default: enabled).
  --collector.netstat       Enable the netstat collector (default: enabled).

On the other hand, I found two records that lost their couple, both have the _receive_ but lost the _transmit_ part:

node_network_transmit_multicast_total - lost (node_network_receive_multicast_total present)
node_network_transmit_frame_tota - lost (node_network_receive_frame_total present)

And these other two are part of the disk family, no vmstat or either netstat, and useful for monitoring. It would be nice to recover them again:

node_disk_sectors_read - lost
node_disk_sectors_written - lost

Thanks,

[SuperQ]

vmstat and netstat are still enabled, it's just that the list is filtered. See the --help output:

      --collector.netstat.fields="^(.*_(InErrors|InErrs)|Ip_Forwarding|Ip(6|Ext)_(InOctets|OutOctets)|Icmp6?_(InMsgs|OutMsgs)|TcpExt_(Listen.*|Syncookies.*)|Tcp_(ActiveOpens|PassiveOpens|RetransSegs|CurrEstab)|Udp6?_(InDatagrams|OutDatagrams|NoPorts))$"  
                                Regexp of fields to return for netstat collector.
      --collector.vmstat.fields="^(oom_kill|pgpg|pswp|pg.*fault).*"  
                                Regexp of fields to return for vmstat collector.

For node network, I said above, those metrics are gone, because they were a bug, and not named correctly in the first place. Please review https://github.com/prometheus/node_exporter/pull/890

node_disk_sectors_.* were removed by https://github.com/prometheus/node_exporter/pull/787 as they duplicate node_disk_.*_bytes_total. You can simply use the bytes metric instead.

[rfrail3]

Sorry, I didn't see that new options, it's fine.

Thanks for the clarification, indeed.
