Does the Application Insights Plugin Work in Microsoft Azure Government?

We have a 4.9.8 Installation running in an Azure App Service. The Application Insights plugin is installed and configured with the appropriate instrumentation key. Wordpress, in this instance, is being used only as a backend with a React application using the data via the WP Rest Api. From what we can tell, Application insights is only logging requests or errors that occur in the UI of the Worpress installation. We can see activity if we browse to /wp-admin/ for example but see nothing for any of the rest endpoints.

I'm trying to work out if we have some misconfiguration or, if the API never loads the plugin and therefore never logs any data.

I get these errors in a continuous loop while debug is turned on. I had to add some code to my WP install in the "_doing_it_wrong" function to find out the culprit, and it was this plugin. Here's a snippet:

Line 33 of the file in question is the if-statement within this function:

function endRequest()
    {
        if (is_page() || is_single() || is_category() || is_home() || is_archive() || is_404())
        {
            $url = $_SERVER["HTTP_HOST"].$_SERVER["REQUEST_URI"];
            $requestName = Common::getPageTitle();
            $startTime = $_SERVER["REQUEST_TIME"];
            $duration = floatval(timer_stop(0, 3)) * 1000;
            $this->_telemetryClient->trackRequest($requestName, $url, $startTime, $duration, http_response_code(), !is_404());

            // Flush all telemetry items
            $this->_telemetryClient->flush();
        }
    }

I don't know why, when, or where "endRequest" is being called, or why it's doing so before the query is run, but it seems kind of important...

Line 10 requires that a file be loaded, but the file isn't included, so the plugin is useless in it's current state.

Hello
Plugin bug on tracking title on certain page :

I don't know if this is this statement

or more complexe regex trouble but it raise on error like that :

Installed on WP 5.1.1

Receiving page request telemetry, but as 0s, 1s, 2s, etc ...
Looks like values are not sent in miliseconds which doesnt provide accurate results.

Also, are the errors captured with this plugin and can we see 500 errors with trace ?
What about dependencies ?

I'm also worried by the fact there were no updates over 2 years :)

Hi,

I'm trying to using this plugin in my Wordpress but once is installed I cannot activate it. I click on Activate button but nothing happens.... It remains deactivated.

Any thoughts?

The plugin is currently appearing as "untested" against the last three major versions of WordPress. Before we use this plugin, it would be good to understand if it is still going to be supported by Microsoft?

I'm trying to use this plugin on my WordPress MU installation of 4.2.2, the following error occured when I activate the plugin

Plugin could not be activated because it triggered a fatal error.
Warning: require_once(vendor/autoload.php): failed to open stream: No such file or directory in D:\home\site\wwwroot\wp-content\plugins\application-insights\ApplicationInsightsPlugin.php on line 10 Fatal error: require_once(): Failed opening required 'vendor/autoload.php' (include_path='.;C:\php\pear') in D:\home\site\wwwroot\wp-content\plugins\application-insights\ApplicationInsightsPlugin.php on line 10

I get the following error after activating the plugin:

Hi folks,
I get the impression this plug-in has been abandoned. Is that correct?
Does it still work in newer versions of Wordpress? Like 4.8.x ?

Thanks...

Hi,

I used this plugin at my blog hosted at HostGator but had to disable it because of few issues.

Suddenly my blog gave frequently error 500 and few times I saw error messages about curl (page rendered still well). I contacted support about server errors and they told me that my site has more processes than allowed for shared hosting. There were not many people visiting blog at this moment and I have had no issues like this even at some high peak moments. Issues disappeared after disabling this plugin.

As I got not much information by hosting support and they were not very interested in helping me. Therefore I have no feedback by their techies about what was going on at server. As far as I understood from mere mortal feedback given by first line support then for some reason my site spawned new processes and at one point it reached the limit.

Is it possible that some libraries used with this plugin start new processes and is there any way to avoid it?

Hello!

When i enable this plugin, memory consumption grow up very high on the servers (classic LAMP).

This is when plugin disabled.

[L root@centos-web02 ~]$ free -h
              total        used        free      shared  buff/cache   available
Mem:           7.7G        1.0G        4.3G        352M        2.4G        6.0G
Swap:          2.0G        326M        1.7G

And this when enabled.

Something seems to be missing in this repo. It seems you have to install composer before you can add the plugin to your Wordpress site. Would it be possible to include all the required files in this repo?

Hi,

Application Insights is not logging correctly when using your plugin. I raised a bug with Microsoft. They have updated their JavaScript. You can now updated it:

Hi all I have a wordpress installation inside a docker container running on azure appservice for Linux.

The plugin has started creating exceptions that made the server unresponsive.

Unfortunately I don't have the docker container logs. Because we re-imaged the server in order to recover, but it clearly stated an exception while trying to access an application insights http route. One more indication for this is that no exception/http500 ever was retrieved and shown in the app insights failures tab. Only the azure AppService http500 chart traced the problem (this is essentialy reported by the proxy/loadbalacer which runs on windows).

I will try to recover the logs and post back if possible.

Is there by any chance a reason why this may be happening.

On PHP 7

PHP Fatal error: Uncaught TypeError: Argument 1 passed to ApplicationInsights\WordPress\Server_Instrumentation::exceptionHandler() must be an instance of Exception, instance of Error given in D:\home\site\wwwroot\wp-content\plugins\application-insights\src\Server_Instrumentation.php:56

I've just tried to upload the code to an existing Wordpress site. I see the plugin in the WordPress admin plugin page but when I try to activate the plugin I get this:

Warning: require_once(vendor/autoload.php): failed to open stream: No such file or directory in /var/www/html/wp-content/plugins/ApplicationInsights/ApplicationInsightsPlugin.php on line 10

Fatal error: require_once(): Failed opening required 'vendor/autoload.php' (include_path='.:/usr/share/php:/usr/share/pear') in /var/www/html/wp-content/plugins/ApplicationInsights/ApplicationInsightsPlugin.php on line 10

Where is the /vendor/ stuff supposed to come from?

This is a Wordpress site running in a Ubuntu VM in Azure.

Hello @SergeyKanzhelev, I saw that you've started making commits to this repo in May. Before that, the commits stopped for about 2 years (2016 and 2017).

Is this repo being maintained now?

Thanks!
