I am using python 3. In the below code I am getting exception:

try:
utf8_signs = bytes(signs).encode("utf-8")
print("utf8_signs = {}".format(utf8_signs))
except Exception as e:
print("Exception occurred: {}".format(str(e)))

Thanks! I was able to reproduce the same exception . I'll fix this and get back to you short

from azure-log-analytics-data-collector.

@jahidakhtargit please install new package azure-log-analytics-data-collector-api 0.2.0

pip install azure-log-analytics-data-collector-api --upgrade

from azure-log-analytics-data-collector.

@yokawasa, thanks for the info. Will upgrade and let you know.

from azure-log-analytics-data-collector.

@yokawasa not working, same exception I'm getting

from azure-log-analytics-data-collector.

@yokawasa Exception in the below code, nothing to do with azure here it seems.

signs = "POST\n{}\napplication/json\nx-ms-date:{}\n/api/logs".format(str(content_length), date)
utf8_signs = None
try:
utf8_signs = bytes(signs).encode("utf-8")
print("utf8_signs = {}".format(utf8_signs))
except Exception as e:
print("Exception occurred: {}".format(str(e)))

from azure-log-analytics-data-collector.

@jahidakhtargit Please make sure if you have installed the latest package - azure-log-analytics-data-collector-api-0.2.0

$ pip install azure-log-analytics-data-collector-api --upgrade
$ pip list |grep azure-log-analytics-data-collector-api
azure-log-analytics-data-collector-api 0.2.0

Or if you're directly using source code in Github, please git clone the latest code:

• https://github.com/yokawasa/azure-log-analytics-data-collector/blob/master/python/datacollectorapi/client.py

As you can see, the latest __signature function in client.py is like this:

    def __signature(self, date, content_length):
        sigs= "POST\n{}\napplication/json\nx-ms-date:{}\n/api/logs".format(
                            str(content_length),date)
        utf8_sigs = sigs.encode('utf-8')
        decoded_shared_key = base64.b64decode(self.shared_key)
        hmac_sha256_sigs = hmac.new(
                decoded_shared_key, utf8_sigs,digestmod=hashlib.sha256).digest()
        encoded_hash = base64.b64encode(hmac_sha256_sigs).decode('utf-8')
        authorization = "SharedKey {}:{}".format(self.customer_id,encoded_hash)
        return authorization

Please try with the latest package or source code

from azure-log-analytics-data-collector.

@yokawasa, pulled the latest code. Now it's working. Thanks for the help. One more thing, Custom log is now created in my log analytics workspace, but not able to see any data. How long does it take for the data to appear in azure?

from azure-log-analytics-data-collector.

@jahidakhtargit
There are factors that affect the latency. From my experience, it's somewhere between 5min and 10min. It may be improved in the future but I don't know. The latency I mean here is the time it takes for log data to become available after it's collected.

I'm closing this issue but please feel free to re-open if you have further discussion.

from azure-log-analytics-data-collector.

@yokawasa, is there a way to delete the log created through code in azure?

from azure-log-analytics-data-collector.

@jahidakhtargit
I haven't tried but it seems you can delete the log with Purge API. here are references:

• https://docs.microsoft.com/en-us/azure/azure-monitor/platform/personal-data-mgmt#delete
• https://docs.microsoft.com/en-us/rest/api/loganalytics/workspaces%202015-03-20/purge
