I'd like to put iccube under solid monitoring so that we know when a) cube load failure or b) cube last update time exceeded the expected.
is there an api i can use to integrate with standard monitoring tools?rest, command-line etc ...
thanks in advance, assaf
Regarding the schema load failure you can check the notification service (www); you can for example receive an eMail on failure. Note that you can implement (JAVA) your own transport service to receive notifications. There is no "notification" for last update time exceeded but if you could use an external LOAD command (www) for loading your schema; in that case you will know the last update time and perform whatever logic required.
Edit: XMLA commands can be sent via any tools (e.g., Bash).
Hope that helps.

We have a Multitrack web conference implementation using AMS 2.4.1 version. Its working great for our use case, except in one scenario. When there are N (< 3) number of users and they on there camera simultaneously, then few remote users are not rendered as we don't receive the video tracks for those users in newStreamAvailable. We only receive the audio track for those users. We are able to reproduce this quite frequently.
As a backup, I am trying to poll AMS using getTrackList with the main track Id to get all available streams, but I am not getting any message trackList
var jsCmd =
{
command : "getTrackList",
streamId : streamId, // this is roomId or main track id
token : token
}
Any insight would be helpful.
Thanks,
We were able to resolve the issue, posting here to help anyone who might be facing a similar issue.
With push notifications from the server, we might encounter issues when for some reason push operation doesn't succeed. In that case, it's better to have a backup plan to pull from the server and sync.
The Ant Media Server suggests pulling the server periodically for the room info. The server will respond with active streams and the application should synchronize.
For reference, please refer to following link https://resources.antmedia.io/docs/webrtc-websocket-messaging-reference
I want to schedule a telegram bot message to be sent at a specific unixtime.
As from telegrams official api (https://core.telegram.org/api/scheduled-messages) that should be possible by setting the schedule_date flag.
To schedule a message, simply provide a future unixtime in the schedule_date flag of messages.sendMessage or messages.sendMedia.
However I was not able to set that flag. To be more precisely, I do not even know how to set a flag, or if I am using the correct api.
What I have tried is to use the api directly via the browser (could use curl as well) like so: https://api.telegram.org/botBOT:TOKEN/sendMessage?chat_id=ID&text=Test&schedule_date=1653503351
I also did not find any way to access this flag via https://pypi.org/project/pyTelegramBotAPI/#description https://telepot.readthedocs.io/en/latest/#send-a-message, nor https://github.com/nickoala/telepot.
I want to implement this feature in a python environment, but any working suggestion would be much appreciated.
EDIT:
I decided to save the intention to send a telegram bot message at a certain unixtime in a database. I then create an infinite loop that checks if there are any unsent messages before the current timestamp. If the loop detects such a message it sends the message and sets a flag, that that message has been sent.
And as promised, here is a fully dockerized example of that behaviour in action: https://github.com/Sokrates1989/nameTheCountDown-lightweight
It creates a bot that you can pass a name and the duration. Once the duration has passed it sends a message with the passed name. Basically a simple countdown that you can give several names, that run simltaniously. As it is a telegram chat, you can modify the way you are informed about the end of a countdown by modifying the notificaiton of that chat.
And here is the Bot in action: http://t.me/NameTheCountdownBot
We can't do this by bot API itself, and there's no schedule_date parameter in sendMessage method:
https://core.telegram.org/bots/api#sendmessage
And what you've read is for Telegram clients, not bot API consumers.
If you don't really need unixtime, you can simply create a table for scheduled messages with a text, chat_id and a publish_time column (like 22:15), and run a command every minute to look if there's a message for current time to send. Then send the message and delete the record.
Note that the python-telegram-bot library has a built-in solution for scheduling tasks: The JobQueue. This feature is based on the APScheduler library, which you can ofc also use without python-telegram-bot.
Disclaimer: I'm currently the maintainer of python-telegram-bot.
https://core.telegram.org/method/messages.sendScheduledMessages
Now you can send scheduled messages right away
I am ingesting json data from EventHub to my ADX-Kusto database table. Till here it is fine. Suppose If Ingestion fails due to some corrupt data, I could use the command .show ingestion failures | project <specific columns> to display the failure ingestion results. But When I try to wrap the command in-side a function, It throws Error. I get to know that we can't wrap control commands inside a function.
Now,
I want to trigger a function whenever ingestion failure happens.
Alert email notification if possible.
One solution I can offer you is to use Microsoft Flow or Azure Function to perform this task - periodically look for failures and issue mails.
There is no support for triggering anything by an ingestion failure - at high rates this simply is unfeasible.
Going forward we are planning to offer additional options for monitoring the ingest operations. Stay tuned.
UPDATE: it is now possible to monitor all ingestion operations using Diagnostic logs. Azure Data Explorer ingestion operations monitoring is now available in preview.
I am trying to execute a simple Wordcount stream application but I face the error "Could not create internal topics - Stream-thread exception"
I have seen a similar thread but that seems to be more of a network issue.
Here is no security enabled on the kafka broker.
Only one broker is configured and still this issue.
Can someone let me know how to fix this?
Clean your temporary kafka queues.
Run --list command on kafka to see all the queues starting with your names and ending with -changelog & -repartition and manually run delete on them.
This one worked for me.
Also, check your settings on delete.topic.enable for actual deletion happening. It was not the default setting until 1.0.0 - see https://issues.apache.org/jira/browse/KAFKA-5384
i have connected to kafka using kafka tool and delete them manually
I am using spring-boot-1.4.0. In my project i am using sentry for logging, sometimes log events are not reflected in sentry.While browsing google about this issue i saw something called "Raven-Sentry" but it was written using Python. Is there any Raven-sentry available for spring-boot.I am using following Raven-callback but still I am unsure how to curl or create a rest endpoint which would let me know the status of sentry whether it is up or down. Please let me know for any more details even i am ready to provide a code samples if needed.
Your help should be appreciable.
As per Brett comments I have updated my question by providing Python Sentry connection test link:
Python-sentry-test
In the above link they are running the test to find out connection to sentry is successful or not. Similarly i want to check the connection to sentry is successful or not via spring-boot.Also i would like to add sentry status to health check, so that when ever my logging events are not reflected in sentry, immediately i will flip the health of sentry to down.
