I can successfully save my logs to Table store for a continuous WebJob, following these instructions:
https://azure.microsoft.com/en-us/documentation/articles/web-sites-enable-diagnostic-log/
However, if I make the WebJob scheduled (runs once every 5 mins), the logs do not show up in Table store. Is this a known limitation (and if so, why?), or does anyone know a way to make it work?
Note: I can see the logs in the Azure Portal, so I know the job runs correctly -- I just want to save these to a WADLogsTable.
Thanks!
Maybe your problem is related to this. Compress in a .zip the Release folder of your web job and then go to your azure webpage, click web jobs and add. Set your schedule in the menu that shows when you press add, you can change it later in your azure web job schedule menu.

I know I can delete old files manually but I need to automate the process. Some cron script would do the job but as far as I know when the app service will be reproviosioned my changes will be lost.
The App Service runs Ubuntu.
Yes, by default, logs are not automatically deleted (with the exception of Application Logging (Filesystem)). To automatically delete logs, set the Retention Period (Days) field (it's one of the way to do that).
You could automate the deletion by leveraging KUDU Virtual File System (VFS) Rest API. For a sample script, checkout this discussion thread for a similar approach.
While WebJobs is not yet supported for App Service on Linux.You could use Azure Functions for running scripts, if your requirement fits.
We have a requirement where we want to create a scheduled web job to call an API and process some data at the 12:00 AM every night. However, each of the job needs to be triggered at 12:00 AM of specific time-zone, to which the record in the table belongs.
Is it possible to automate the creation of web job with scheduled time, after an entry is done in the table? The time zone information along with other inputs, required by the API, will be in the table record. As far as I have googled, I am not able to find if it is possible to automate the creation of web job after an event.
If you have the executable ready as a zip you can upload that zip to your App Service Web App as a Webjob using the Webjobs API.
I have been running my web jobs for a few months now and the history includes hundreds of thousands of instances when some of them ran, mainly TimerTriggers. When I go in the portal to the "Functions" view of web jogs logs I have noticed that my app service plan shoots up to 100% CPU while I am sat on that page. The page constantly says "Indexing...."
When I close the "Functions" view down the CPU goes straight back down to a few percent, it's normal range.
I assume it must be down to the fact that it has been running for so long and the number of records to search through is so vast. I cannot see any option to archive or remove old records of when jobs ran.
Is there a way I can reduce the history of the jobs? Or is there another explanation?
I'm not familiar with Azure Web Jobs, but I am familiar with Azure Functions which is built on top of Web Jobs, so this might work.
In Azure Functions, each execution is stored in Azure Storage Table. There, you can see all of the parameters that were passed in, as well as the result. I could go into the Storage Table and truncate the records I do not need, so you might be able to do the same with Web Jobs.
Here is how to access this information:
Table Storage in markheath.net/post/three-ways-view-error-logs-azure-functions
Based on your description, I checked my webjob and found the related logs for azure webjobs dashboard as follows:
For Invocation Log Recently executed functions, you could find them as follows:
Note: The list records for Invocation Log are under azure-webjobs-dashboard\functions\recent\flat, the detailed invocation logs are under azure-webjobs-dashboard\functions\instances.
I am using the default logging mechanism that Azure web job provides. Type of logger is 'TextWriter'. I have 3 functions in the same web job with extensive logging. A number of logs being generated every minute. As with the default settings of azure web job, all the logs go to the storage account into blobs. I do not want my storage account to just keep on growing with months and months of old logs.
I need a way of cleaning the logs on a periodic basis. Or is there any setting/configuration that can be done so that my logs get cleaned on a periodic basis? Or should I write code to monitor the blob container 'azure-webjobs-hosts' and then the files inside 'output-logs'. Is that the only place where the logs for my application are stored by default by the web job?
I tried searching the web but couldn't find any related posts. Any pointers would be of great help.
Based on my experience, we can achieve this purpose by define the azure storage container name. We can define weekly/monthly/daily as container name. Then use a time trigger function to delete the container. For example, if we need delete weekly data, then we set container for this weekly data, then delete it in the next week via time trigger.
I have a Azure Scheduled Web Job on Azure WebApp. Inside web job, it downloads the excel file from azure blob and read (25 - 30 k records in a file), then it iterate through loop to insert's records in database. Now, when we schedule (Schedule time: 18 hrs) first time the job ran successfully and processed all records from file without any interruptions (between this time site was accessing). But, next time it fails (Aborted) without any reason (No one was accessed site. may be in idle state).
WebJob Abort Status
There is no any indications when i looked into logs. However, first schedule ran successfully and shows success status later all are in Aborted status, Why?
Success
Also done with below settings in webapp:
stopping_wait_time - 3600
WEBJOBS_IDLE_TIMEOUT - 3600
SCM_COMMAND_IDLE_TIMEOUT - 121
Per Azure's documentation,
Always On. By default, web apps are unloaded if they are idle for some
period of time. This lets the system conserve resources. In Basic or
Standard mode, you can enable Always On to keep the app loaded all the
time. If your app runs continuous web jobs, you should enable Always
On, or the web jobs may not run reliably.
So there is no promise from Azure Web Apps for your WebJob to continue running more than 20 minutes. If you need to rely on that you'll need to enable Always On. To enable it. See below.
In the Azure Portal, navigate to your App Services.
Click Application Settings in the SETTINGS menu.
Turn Always On to on, then click Save.
