Automate disabling @channel & @here notifications using private Slack API

10.17.2019 by William Lam // Leave a Comment

Slack is a popular communication and collaboration tool which has been adopted by many organizations including the one I work for. I am a fan of Slack and use it on a regular basis. Like most users, I am a member of several different workspaces and a ton of different channels.

I think most Slack users would agree that one of the most commonly miss-used feature of Slack is the @channel and @here notifications which allows a user to broadcast a message that notifies everyone within a specific channel. I most often see this when a user is looking for immediate assistance and think that this is the best way to get help, it is not. In some cases, inpatient uses end up spamming multiple channels which can have up to 1K+ members! As you can imagine, this type of behavior is usually not well received.

This is the modern day "reply-all" email storms that I am sure many of you have at experienced at least once if not many more times within your organization 🙂 Slack does provide a few ways of disabling notification, either within the workspace but this would disable the feature completely and I do see value in this feature when used correctly or disabling notifications on a per-channel basis as shown in the screenshot below.

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.
