Forwarding VMC Events to Slack using Log Intelligence Webhook

06.04.2019 by William Lam // Leave a Comment

VMware Log Intelligence (LINT) is a public VMware Cloud Service that is available to all VMware Cloud on AWS (VMC) customers. LINT provides customers with a unified view of their SDDC infrastructure including vSphere, NSX and vSAN from a logging standpoint and LINT can also be used with an on-premises deployment. The LINT team recently published a nice overview here, which I highly recommend a read.

One really interesting capability of LINT is the alert and notification feature, which includes UI and email, but what really stood out to me with this feature is that you can also trigger a Webhook! This means you can literally integrate with any external system including public cloud services that can receive or process a Webhook. Some examples can include publishing to a specific Slack channel, sending an SMS to your SRE team, an alert in PagerDuty or even calling an AWS Lambda function. The possibilities are truly endless on what you can do with a Webhook integration!

For our recent VMC Customer Summit, I thought it would be really cool to show off some demos on what you could do with LINT Webhooks. In this blog post, I will show you how to use the If Then This That (IFTTT) service which natively supports Webhooks and publish a specific VMC event into a Slack channel. Slack also supports native webhooks, but using IFTTT, you can apply this example to other Cloud Services that you may want to integrate with.

How to get notifications when a component on the VMware HCL changes?

11.05.2014 by William Lam // Leave a Comment

Last night, I received a pleasant and surprising email, you can see the details in the screenshot below:

This was a surprise because it was something I was tinkering around with back in March (8months ago!) to see if I could some how generate notifications when changes were being made to a specific component/device on the VMware HCL also known as the VCG (VMware Compatibility Guide). I suspect many of you have used the VMware HCL at least once if not many more times and as you can imagine, it would be nice to be able to get notifications or alerts when something has changed for a particular component or device that you might care about.

I was thinking about this problem because at the time I was interested in receiving updates on a particular VSAN disk controller. While browsing through the HCL, I had noticed there was an RSS feed icon located on the upper right hand corner for each component/device as shown in the screenshot below.

I thought maybe I could do something interesting with that? I decided to use one of my favorite SaaS services IFTTT (If This, Then That) which I have blogged about in the past on how to send SMS notifications using vCenter Server Alarms. I found an RSS to Email IFTTT recipe and created a notification based off of one of the Intel RAID Controllers by specifying the RSS feed URL.

I knew this was going to be a bit difficult to test given the HCL does not get updated that frequently and even if it does, I have to be monitoring the right device that received the update. I completely forgot about this recipe until yesterday when I had received the email stating an update had been made to this device. I guess it worked after all 😀 If there specific things you care about on the VMware HCL and you want to be able to receive notifications for any updates, you can create several IFTTT recipes that can either send you an email or notify you through some other method. I think this is a pretty nifty trick instead of continuously checking the VMware HCL every so often for changes, unless you are looking for brand new component/device that has not been added to the HCL.

How to Send vCenter Alarm Notifications to SMS & Other Online Services Using IFTTT

02.02.2013 by William Lam // 2 Comments

I just discovered a pretty cool free online service called IFTTT (If That Then This) which allows you to easily create what is known as a recipe that is composed of trigger and an action to send a notification. This can be thought of like a vCenter Alarm with a trigger and action, but in IFTTT's case, a trigger and action can be almost anything such as an email, facebook event, twitter, etc.

I stumbled onto IFTTT while going through some of my unread blog feeds this morning since I could not go back to sleep after randomly waking up at 4am in morning. I was reading an article from Matt Cowger about something called a Pebble which I had not heard of before and it peaked my interest. In reading about Pebble (pretty slick actually), I learned about IFTTT which is one of the notification systems Pebble supports. I decided to give IFTTT a try and to see how easy it would be to setup SMS notifications for a vCenter Server alarm.

Step 1 - Sign up for IFTTT account, you need to ensure the email account that you use to register is the same account that will be used to send the trigger.

Step 2 - Create a new Recipe using email as the trigger and SMS for the action. The process is very straight forward, just follow the wizard and at the end you will enter your phone number for SMS notification and confirm with a code.

Step 3 - Create a vCenter Alarm for the event you wish to trigger off of and set the email address to send to *protected email* as noted in the Recipe.

Step 4 - In my test, I created an alarm for a Powered Off event and went ahead and powered off a VM to generate the alarm.

Step 5 - IFTTT checks the triggers every 15minutes. If you do not wish to wait 15minutes you can force a check by clicking on Check Now button in the Recipe.

Step 6 - If everything was setup correctly, you should have received a text message with the details of the vCenter alarm. In my Recipe, I configured it to only send the Subject which contains everything you would need to know about the vCenter alarm, at least for you to decide whether or not you want to investigate the issue.

The possibilities are pretty much endless in terms of the triggers and actions that you could create with IFTTT, I even created one for my ghettoVCB backup notification. The only downside that I noticed while giving IFTTT a try is that the trigger check is every 15minutes which could be a bit long for things requiring immediate attention, but I also read that there are certain Recipes that supports a "Quick Trigger" which would then execute immediately upon receiving. I think for a free service this is very cool and much easier than setting up your own SMS system. I would recommend giving IFTTT a try and see what cool Recipes you can build and integrate with your VMware or other environments.

I hope my body will let me crash and get some sleep now ...
