Played around with argus, made errors and now argus will not start anymore

[peschau]

Hi,
very new with argus, I played around with some services from the examples which I like to handle and everything was fine. With a little bit try and error I managed my first self build service.
While creating the next one, I put some errors in the config.yml and argus stated: will not start

Unfortunately even with removing the "new" service or shorten the config file to only one service, which was running in the past, the message stays. Restarted the machine, no changes.
Erased the Database, no changes.

Started Argus with:

./argus -config.file config.yml

and got:

root@DockerTest:/opt/argus# ./argus -config.file config.yml

Then I started this document, did some screenshots and of course I need some time for this. Missing the last of the above messages, I repeated the "./argus -config.file config.yml" and did not get any errormessage as before and the service is now again starting without any problem.

How does the problem overcome several reboots but will heal after writing in the discussion section in github. Is there any timer which has to expire?

Peter

Just restarted (without any Changes) the Service and are again Back to the Error as described above.

[JosephKav]

Could I ask what version you're using and maybe a bit of the config that's causing the fail?

[JosephKav]

That crash looks like it's from the GitHub query failing, possibly related to their rate-limit. Then it crashes when it tries to log that error because of a mistake in 0.20.0 that doesn't have the logger initialised before a few checks. This is fixed in #529. I'll do a release of this now for you

[JosephKav]

0.21.0 should fix this crash for you @peschau. Let me know if you face any more issues. Happy to help :)

[peschau]

Hi Joseph,
as I'm new with Argus, I use of course the latest available version (0.20.0) :-)
Rate limit seems to be a valid reason, as I was not aware, that there is one, I restarted argus quite often.

The problem is, that I'm not able to get the Version info of the installed Version of Tandoor Recipes.

This is the answer of the "openapi" call:

HTTP 200 OK
Allow: GET, HEAD, OPTIONS
Content-Type: application/vnd.oai.openapi
Vary: Accept

openapi: 3.0.2
info:
  title: Django Recipes
  version: 1.5.24
paths:
  /api/plan-ical/{from_date}/{to_date}/:
    get:
      operationId: retrieveget_plan_ical
      description: ''
      parameters:
      - name: from_date
        in: path

And I need the 1.5.24 of course but I'm not shure how.

Thought of:

json: info.version
regex: ([0-9]+\.[0-9]+\.[0-9]+)

but did not get it to work. Will give it a try now. And thanks a lot for your fast, no, very fast reply and fix.

Regards Peter

[JosephKav]

That looks more like a YAML response rather than JSON from that API request. A JSON would have the key:values in quotes, and the whole thing in curly brackets, e.g. { "info": {"title": "Django Recipes", "version": "1.5.24"}}
To get that version, I'd say to try
regex: 'version: (\d+)'

[JosephKav]

About the rate-limit. GitHub has a limit of 60 unauthenticated requests per hour. If you create and use an access token, you can do up-to 5000 requests an hour - https://github.com/settings/personal-access-tokens/new

Hi Joseph,

now I see the "Problem" in the journal:

Feb 09 20:40:45 DockerTest argus[174422]: VERBOSE: Tandoor Recipe, Tracking Tandoor Recipe at https://github.com/TandoorRecipes/recipes every 10m
Feb 09 20:40:45 DockerTest argus[174422]: WARNING: Tandoor Recipe, rate limit reached for GitHub 

And a little reading with the Help of Google and in real paper:-) fixes the "unmashalling Error" which I get with

`regex: version: (\d+) (without the quotes you described:-))

So I found two solutions, unfortunately I'm not really clear why they are both working, anyway

regex: 'version: ([0-9]+\.[0-9]+\.[0-9]+)'   
regex: version:.([0-9]+\.[0-9]+\.[0-9]+)

will both work,

(\d+)

with both versions above, only gives back a "1" instead of "1.5.24". My regex book is telling the same as you did, but I could not get it to work.

Regards and thanks for your Help
Peter

[JosephKav]

Oh yeah, that regex I sent was only matching the first number set, 'version: ([\d.]+)' was what I meant to put!
The \d is the same as [0-9], so my regex was just capturing the "1" in "1.5.24" and not matching on the .s. Your regex is probably what you want as it's stricter, forcing the version to be 3 sets of numbers - MAJOR.MINOR.PATCH

regex: 'version: ([0-9]+\.[0-9]+\.[0-9]+)' - This has to be in quotes because otherwise, when reading the YAML, it thinks that you might have forgotten a newline between regex and version, e.g.

regex: 
  version: '([0-9]+\.[0-9]+\.[0-9]+)'

So you need it in quotes to show that the value of the regex key is that whole string.
regex: version:.([0-9]+\.[0-9]+\.[0-9]+) - Here the . gets around that by making the value bit look like one string.

(Doing this via the UI should allow you to test that it can get the version and also save it in the correct formatting)

[peschau]

Hi Joseph,

is the UI mentioned in the documentation? If so, I missed it. But with your help, I found it. Will give it a try.

Anyway, thanks for the help and the hints. I learned something new and I think, I have to brushup my regex skills.

Regards Peter
