Our redraw sometimes changes our position on the page, possibly due to our divs not having fixed sizes?

Unsure how this happens:

$ ls *Via* *GET* *OPTIONS* -l
-rw-r--r-- 1 ahu ahu 24 2015-10-20 15:47 GET.0
-rw-r--r-- 1 ahu ahu 24 2015-10-20 15:41 OPTIONS.0
-rw-r--r-- 1 ahu ahu  8 2015-10-20 15:41 Via:.0

Can we have the option to set up multiple carbon servers in powerdns?

I already fiddled with the code, but so far I'm too successful, however; I wish to be able to sort servers in the dropbox overview, using the <optgroup> tag.
People may like to order based on node-location or function (auth/rslv) or whatever.

It will be close to impossible to program matches on hostname, but maybe it's possible to make a default <optgroup> + allow to define custom ones, and have a key/value list of known hosts, which would place them correctly in the generated HTML.

Current interpolation & derivative stuff is nice, but stupid. It would be better to generate the derivative from the cspline. We deal badly with missing data now

Hello,

I tried to download Metronome from this link : http://bitbucket.org/eigen/eigen/get/3.2.1.tar.bz2 .
But the link seems to be dead...
If someone have a up to date procedure, I'm a taker !

Most of the time when I try and load metronome1.powerdns.com with a cold browser cache I get a Javascript error and have to refresh the page.

The error message:

After dismissing the error the page loads slightly further but no graphs are visible. A refresh fixes the problem.

Observed on Chromium (latest) on various machines all running Debian Stable x86_64.

If you're using dnsdist to frontend various backend powerdns recursors, then you've got a dnsdist queries value thats not being graphed on "All". At the moment the callback for the All graph only includes powerdns servers' queries and servfails. It would be nice to have dnsdist query metrics represented on that All graph somehow in that scenario.

Support users/groups, either by making it easy to run multiple metronomes, or writing actual code.

carbon-relay sends data only over pickle protocol, metronome only accepts plaintext

Hi,

I have an issue after installing with git clone and did turn on the server, am having: 404 File not found

is there any other configuration? that I need to do

local.js edited and same issue.

I have local changes in /usr/share/metronome/html/local.js namely
"use strict"; var metronomeServer="/metronome-data/";
to host it behind a reverse proxy but it seems that the debian package update overwrites it to its default.

hi metronome 0.9.0+52.g877231f0d-1pdns.stretch amd64 mini-graphite with builtin webserver and client-side plotting

The Debian way would be to make it a symlink to /etc i suppose. Any chance of mitigating this?

thank you,

Stefan

I seem to have all the listed dependencies. What am I missing?

Is it possible to easily modify the code to output a stacked graph, showing each of the individual pdns instances on a single graph instead of the sum?

Metronome uses an older version of yahttp that sets Transfer-Encoding chunked and Content-Length at the same time, which is not allowed and causes problems with newer HTTP clients that check this, like recent versions of NodeJS.

Solution: recent versions of yahttp fix this issue.

See:

• PowerDNS/pdns#3723
• cmouse/yahttp#12

Our storage is sorta naive. Turns out that what graphite does isn't that great either.

metronome forks a connection for each carbon connection, which often seem to never close (had over 600 threads running for 3 pdns sources)

also it reads only single bytes from network due to unbuffered line reading (check with strace).

metronome does not seem to be responding to or even receiving packets on port [::]:8000 when daemonized.

When started via

$ ./metronome --daemon=0 --stats-directory=./stats
Launched Carbon functionality on [::]:2003
Launched webserver on [::]:8000

it works as advertised.

Currently, the longest duration of the metrics displayed by metronome is 1 week.
It would be great to allow to visualize graphs up to one month.

In one graph showing percentage CPU use, there was only one number, 50%, plotted on the vertical axis. With only one number it's hard to know the scale of the graph. It could be drastic or it could be minor and the user would have no way to know what the scale is.

Thanks

When querying a data range for which metronome has no data, it should return null values instead of 0. Currently it's not possible to distinguish between missing data and data that is simply 0.

Care must be taken to not break the current graphs with such a change.

To test, pick an end time in the future.

Currently the metronome API only supports JSONP, which wraps the data in a function call. This makes it harder to consume from other code.

When the callback argument is not present or empty, it should return plain JSON instead with Content-Type: application/json.

Additionally, the data returned by the retrieve call is invalid JSON (but valid Javascript, so browser JSONP calls work): raw and derivative need to be wrapped in double quotes.

Uncomming the bottom of Makefile.am makes make check work for me, but we actually need some autoconf/automake changes to correctly detect the relevant Boost lib, make the files show up in make dist, etc.

At least for some flavours of Linux..

Useful once the 'get settings from URL' feature is implemented

Needs a config file & command line parser.

The overview "All" on metronome1 sees to be broken. I could verify this but it first worked until I got more and more servers into my own metronome. There are absolutly no broken data files in my own metronome.
Could please fix this issue.

It seems that 24 servers is the magical number if you add the 25. server it is broken.

it is microseconds but there is no way to tell

when I run make I get the following error message:

When build I get error.

And that is with newest ubuntu. Really it requires so new library version?

Would be nice to show some sort of error message in the HTML/JS files when the connection to the metronome server fails or runs into a timeout.

Kept wondering why a white page without any content seems to be interesting for everyone else (who doesn't have port 8000 blocked outbound) ;)

Currently, at the bottom of the metronome html web-page it is hard-coded the string below

Built with Metronome. You are most cordially invited to add your own PowerDNS instances to this "graph as a service". It can be as easy as setting: carbon-server=82.94.213.34, or at runtime: rec_control set-carbon-server 82.94.213.34

It would be great to provide a way through the local.js file to

• customize the content of the string
• specify an external-address variable to replace the currently hardcoded 82.94.213.34 IP address

It would be great to add a boolean flag to the local.js to optionally disable the Github banner.

Metronome should be a daemon too
