Indeed, it looks pretty strange... Could you try with an older version of rrdtool (like 1.4.7) ?
From @fionnb on February 21, 2016 16:30
confirmed:
Looks like the output is a bit different with 1.5.5. Anyway, 1.5.5 should have a working JSON output (unlike 1.4.7), I'll make a change to use it if present.
From @fionnb on February 22, 2016 9:31
I get it that 1.4.4 does not have the fix yet?
You're right. The stats plugin has its own repository (https://github.com/modoboa/modoboa-stats) so this issue is misplaced.
From @fionnb on February 22, 2016 10:27
I am sorry then. Should I open an issue there or just wait for an update to appear? Feel free to close this issue if inappropriate.
Don't worry, I'm going to move this issue.
The above output shows that the timestamps are missing. This is true for the JSON output as well.
I had a look at the rrd codebase and recognized that it's required to use the --showtime
flag to get timestamps in the output.
The fix is easy:
Change line 103 from
cmd = "{} xport --start {} --end {} ".format(
to
cmd = "{} xport --start {} --end {} --showtime ".format(
@awein Great, thank you ! I guess this option has been added to rrdtool 1.5.x, right ?
@tonioo on the changelog, http://oss.oetiker.ch/rrdtool/pub/CHANGES
RRDtool 1.6.0 - 2016-04-19
==========================
* re-introducted --showtime option on rrdxport
I don't see in the changelog, when this option have been removed
Too bad ubuntu 16.04 still has 1.5.5 and that version does not have the showtime option :-(
Helo Guys,
first...sorry my bad english : |
Im getting a message "internal error" when i try to see the stats into modoboa 1.5.3
I tried edit the file graphics.py removing the option "extra_args" and "{}" to try to solve the problem but I stiil getting the message and the graphics dont show up.
Im using Ubuntu 16.04 with rrdtool 1.5.5
As fionnb told, the rrdtool 1.5.5 doesnt have the showtime option
this is part of my current graphics.py: . . . """Export data to XML using rrdtool and convert it to JSON.""" result = [] cmdargs = [] for curve in self._curves: result += [{ "name": curve.legend, "color": curve.color, "data": [] }] cmdargs += curve.to_rrd_command_args(rrdfile) code = 0 for extra_args in [" --showtime", ""]: cmd = "{} xport --start {} --end {}{} ".format( self.rrdtool_binary, str(start), str(end), extra_args) cmd += " ".join(cmdargs) if isinstance(cmd, unicode): cmd = cmd.encode("utf-8") code, output = exec_cmd(cmd) if code: continue if code: return [] tree = etree.fromstring(output) for row in tree.xpath('/xport/data/row'): . . .
and I tried to solve using this way:
. . . """Export data to XML using rrdtool and convert it to JSON.""" result = [] cmdargs = [] for curve in self._curves: result += [{ "name": curve.legend, "color": curve.color, "data": [] }] cmdargs += curve.to_rrd_command_args(rrdfile) code = 0 for extra_args in [" --showtime", ""]: cmd = "{} xport --start {} --end {} ".format( self.rrdtool_binary, str(start), str(end)) cmd += " ".join(cmdargs) if isinstance(cmd, unicode): cmd = cmd.encode("utf-8") code, output = exec_cmd(cmd) if code: continue if code: return [] tree = etree.fromstring(output) for row in tree.xpath('/xport/data/row'): . . .
any idea to solve the "internal error" ?
Best Regards, Ricardo
Could you please enable DEBUG and send a proper stack trace ? (use a debugger in your browser)
Hello Tonioo,
Sorry... but How I get a "Stack Trace" ?
Im using chrome.. and it is showing me these errors/warnings:

Thank you Ricardo
Thanks for your feedback but it is not usefull. Could send the response body instead ?
@tonioo i am not sure whether this is what you want. I am having the same problem with the stats as well

You need to enable debug information. Just set DEBUG to True inside the settings.py file, you should then see the real issue.
Im getting this too on the "Statistics" pane in admin GUI. Ubuntu 16.04 with rrdtool Version: 1.5.5-4. Requested route gives a 500 error - /stats/graphs/?gset=mailtraffic&_=1474661219137 causing "internal error" message in "Statistics" pane.
FYI those trying to use debug, do an "updatedb && locate settings.py". Find the one in your modoboa instance (prob in /srv/modoboa/instance/). Edit it to use True for DEBUG. Restart uwsgi and nginx services. Open chrome console, hit refresh on "Statistics" and look for a server error. Click the link in the error and you should see a debug trace. Click "Switch to copy-and-paste view" on the trace part. Here is an output from mine:

Hi, on a fresh 1.4.3 install I get errors in the stats module.
AttributeError: 'NoneType' object has no attribute 'text'
i went digging a bit and had it dump the command, which is:
rrdtool xport --start -1week --end 1455825274 DEF:size_recv=/mail/modoboa/stats/global.rrd:size_recv:AVERAGE CDEF:size_recvpm=size_recv,60,* XPORT:size_recvpm:"Empfangsgr\xc3\xb6sse" DEF:size_sent=/mail/modoboa/stats/global.rrd:size_sent:AVERAGE CDEF:size_sentpm=size_sent,60,* XPORT:size_sentpm:"Versendegr\xc3\xb6sse"
Apparently, when using this command, the result will not contain any 't' fields:
... and the subsequent code fails. I wonder what goes wrong while constructing the command?
Can I do anything to make it work properly?
Using rrdtool 1.5.5 btw.
