Unable to get eventsources list using REST API

I am trying to get eventsources information using REST API, as documented here.

I am using a small python script to try to get any results, but can only get this output:

<span class="pln">('Response Status:', 406)
('Response Body:', '</span><span class="dec"><!doctype html></span><span class="tag"><html</span><span class="pln"> </span><span class="atn">lang</span><span class="pun">=</span><span class="atv">"en"</span><span class="tag">><head><title></span><span class="pln">HTTP Status 406 \xe2\x80\x93 Not Acceptable</span><span class="tag"></title><style</span><span class="pln"> </span><span class="atn">type</span><span class="pun">=</span><span class="atv">"text/css"</span><span class="tag">></span><span class="pln">body </span><span class="pun">{</span><span class="kwd">font-family</span><span class="pun">:</span><span class="pln">Tahoma</span><span class="pun">,</span><span class="pln">Arial</span><span class="pun">,</span><span class="pln">sans-serif</span><span class="pun">;}</span><span class="pln"> h1</span><span class="pun">,</span><span class="pln"> h2</span><span class="pun">,</span><span class="pln"> h3</span><span class="pun">,</span><span class="pln"> b </span><span class="pun">{</span><span class="kwd">color</span><span class="pun">:</span><span class="pln">white</span><span class="pun">;</span><span class="kwd">background-color</span><span class="pun">:</span><span class="lit">#525D76</span><span class="pun">;}</span><span class="pln"> h1 </span><span class="pun">{</span><span class="kwd">font-size</span><span class="pun">:</span><span class="lit">22px</span><span class="pun">;}</span><span class="pln"> h2 </span><span class="pun">{</span><span class="kwd">font-size</span><span class="pun">:</span><span class="lit">16px</span><span class="pun">;}</span><span class="pln"> h3 </span><span class="pun">{</span><span class="kwd">font-size</span><span class="pun">:</span><span class="lit">14px</span><span class="pun">;}</span><span class="pln"> p </span><span class="pun">{</span><span class="kwd">font-size</span><span class="pun">:</span><span class="lit">12px</span><span class="pun">;}</span><span class="pln"> a </span><span class="pun">{</span><span class="kwd">color</span><span class="pun">:</span><span class="pln">black</span><span class="pun">;}</span><span class="pln"> </span><span class="pun">.</span><span class="pln">line </span><span class="pun">{</span><span class="kwd">height</span><span class="pun">:</span><span class="lit">1px</span><span class="pun">;</span><span class="kwd">background-color</span><span class="pun">:</span><span class="lit">#525D76</span><span class="pun">;</span><span class="kwd">border</span><span class="pun">:</span><span class="pln">none</span><span class="pun">;}</span><span class="tag"></style></head><body><h1></span><span class="pln">HTTP Status 406 \xe2\x80\x93 Not Acceptable</span><span class="tag"></h1><hr</span><span class="pln"> </span><span class="atn">class</span><span class="pun">=</span><span class="atv">"line"</span><span class="pln"> </span><span class="tag">/><p><b></span><span class="pln">Type</span><span class="tag"></b></span><span class="pln"> Status Report</span><span class="tag"></p><p><b></span><span class="pln">Message</span><span class="tag"></b></span><span class="pln"> Not Acceptable</span><span class="tag"></p><p><b></span><span class="pln">Description</span><span class="tag"></b></span><span class="pln"> The target resource does not have a current representation that would be acceptable to the user agent, according to the proactive negotiation header fields received in the request, and the server is unwilling to supply a default representation.</span><span class="tag"></p><hr</span><span class="pln"> </span><span class="atn">class</span><span class="pun">=</span><span class="atv">"line"</span><span class="pln"> </span><span class="tag">/><h3></span><span class="pln">LogicMonitor Technical Operations</span><span class="tag"></h3></body></html></span><span class="pln">')</span>

Did anybody get this type of call working anytime?

Apart from this, I would like to add new eventsources using the REST API. It looks like there is only an import method to get this, using a XML file.

Are there any examples or templates of that XML file?

Thanks and regards.

I finally changed my code to use the SDK. I recognize I didn't use it at the first time as it looked somehow complicated. When I saw this example code I realized it was really simple to use.

Now my code works perfectly! Thanks a lot for your help!

^^ I highly suggest when ever looking at the SDK go here first https://github.com/logicmonitor/lm-sdk-python/blob/master/LMApi.md has all the methods with example code ie https://github.com/logicmonitor/lm-sdk-python/blob/master/LMApi.md#import_event_source

That data dictionary must be converted to JSON before being concatenated with the requestVars. As suggested, try the SDK. Note that the SDK example is auto-generated and in this case is missing the quotes around the path to the file.

I am trying this and found several problems.

When using on the header, the "Content-Type" spec, I always get an error 500 with an "Unknown error" message. I tried removing it and it looks to work better.

Now I am getting a clear "Authentication failed" error message. I think the problem I have now is creating the correct authentication string. As this string is build with, among others, the request details, I don't know how to correctly append this "files" variable (a dictionary object) to the request variable using this piece of code:

<span class="pln">#Concatenate Request details
requestVars = httpVerb + epoch + data + resourcePath

#Construct signature
signature = base64.b64encode(hmac.new(AccessKey,msg=requestVars,digestmod=hashlib.sha256).hexdigest())

#Construct headers
auth = 'LMv1 ' + AccessId + ':' + signature + ':' + epoch
headers = {'Authorization':auth}</span>

In this case, "data" is not a string, but a dictionary containing a file object.

How authorization string should be built for this particular case?

I will have a look at the SDK anytime, as suggested.

Hi again,

I prepared my script to programmatically create the XML file to define new EventSources. I test it successfully from the UI, using "Add" - "From File".

Now I would like to use the API to make such a call. According swagger documentation here, it looks like I need to provide this file as a parameter, but I don't have a clear idea on how to provide that. I tried several methods, but none of them worked so far:

Adding a parameter named "file" to the URL. Something like: "https://XXXXXX.logicmonitor.com/santaba/rest/setting/eventsources/importxml?file=toimport.xml"

Adding a JSON payload like: { "file": "toimport.xml" }

Adding the XML content to the payload: { "file": "<?xml version="1.0" encoding="UTF-8" ?>......" }

Using any of these methods, I always get an error "HTTP 415 Unsupported Media Type".

What am I doing wrong?

Set the content type as multipart/form-data then send a file object as a local file read for python

<span class="pln">header = {'Content-Type': 'multipart/form-data', 'Authorization': 'LMv1....'}
files = {'file': ('file.xml', open('file.xml', 'rb'),'text/xml')}

r = requests.post(url, headers=header, files=files, verify=False)</span>

You would be much better using the SDK though

No problem. FWIW, adding it as a query parameter is one supported way. The other supported way is to specify "2" in the header "X-Version". https://www.logicmonitor.com/support/rest-api-developers-guide/v2/rest-api-v2-overview#:~:text=you can make v2 requests by including a ‘%3Fv%3D2’ query parameter or by including a ‘X-Version%3A2’ header.

Thanks for the clue!!

I solved the problem with my python script. The solution was to include ?v=2 as the first parameter:

<span class="pln">https://xxxxx.logicmonitor.com/santaba/rest/setting/eventsources?v=2</span>

I also found that option to export an eventsource to a XML file using the UI. I hope I can work with that pretty well.

Thanks a lot for your help!

You can get an example XML file by exporting any EventSource from the UI. Just navigate to an EventSource >> More >> Export.

As far as the get request, i get the same thing if i don't specify "2" in the X-Version header. Basically, the endpoint for v1 appears to be only partially implemented. Use v2 of the API.
