Configure log forwarding from Tanzu Kubernetes Grid (TKG) to vRealize Log Insight Cloud

04.27.2020 by William Lam // 1 Comment

As much as I enjoy kubectl'ing logs in real time for troubleshooting and debugging purposes, this usually does not scale beyond a couple of Kubernetes (K8s) Clusters if you are lucky. Even then, you will not retain any of the historical logs which may be required for deeper analysis or for auditing purposes. This is usually solved by having a centralized log management platform and while working with Tanzu Kubernetes Grid (TKG) running on VMware Cloud on AWS, a solution like vRealize Log Insight Cloud (vRLIC) makes a lot of sense.

While browsing through the vRLIC console, I noticed that it supports a number of log sources including K8s which was exactly what I was looking for. However, after going through the instructions in configuring fluentd on my TKG Cluster, I found that that nothing was being sent. After a bit of debugging, I realized a few steps were actually missing that was required to setup this up on TKG Cluster.

I eventually figured it out and will be sharing this feedback with the vRLIC folks but in the meantime, you can follow the instructions below on how to forward both system and application logs from your TKG Cluster or any K8s deployment for that matter which has outbound connectivity to connect to vRLIC.

How to purge all logs in vRealize Log Insight?

02.01.2017 by William Lam // 17 Comments

I had just deployed a new vRealize Log Insight (vRLI) 4.0 instance in my home lab environment to investigate a behavior that I was seeing with another product, non-vRLI related. Due to the nature of the work, I needed to have a pristine vRLI environment each time to study the results. I had already forwarded some logs into vRLI and rather than deploying another instance or re-deploy the current instance, what I really wanted to be able to do is to just wipe all the logs in vRLI but did not see an option within the UI. I also could have used VM snapshots, but was hoping there was a cleaner solution that vRLI provided out of the box.

The next place I looked immediately after was Mr. Log Insight's site aka Steve Flanders blog but there was nothing there about this other than archiving. After a few Google searches, I came across this exact same question on the vRLI Ideas site but sadly there was no solution and it was dated back in 2014. Though Steve makes a good point about just letting the logs rotate out automatically, in my case, this was not an option and I needed a pristine environment.

Being the curious one, I figured there has to be a way, even if it is not officially recommended nor supported. As you probably have guessed, I did find a way but I would caution that you read the disclaimer below before proceeding further. This was something I needed to do in my lab to test a few scenarios that was non-vRLI related, but I needed syslog target, so this is why I am using vRLI 🙂

How to customize the login UI for vRealize {Operations Manager, Log Insight, Automation}?

03.09.2015 by William Lam // 9 Comments

With so much excitement and positive feedback (internal/external) regarding my article on customizing the login UI for the new vSphere 6.0 Web Client, I knew it was only a matter of time before folks started asking about customizing other VMware login UIs. As I have mentioned already, going beyond just the aesthetics such as adding an organizations logo or colors, it is often a mandatory requirement for many organizations to display a security or warning banner to users prior to logging in. I was recently added into an internal Socialcast thread asking whether it would be possible to do the same for vRealize Operations Manager (vROps).

I figure I take a quick look to see if this was possible and what it might take. I wanted to also take this opportunity and share a few other solutions that other VMware folks have found in terms of customizing the login UIs for both vRealize Log Insight (thanks GSS Engineer Alan Castonguay for sharing the details) and vRealize Automation (thanks to Justin Jones for his awesome tool). You can find all the details below as well as some additional tidbits through my exploration.

Something that can be helpful in the future as more products integrate with vCenter's SSO (PSC in vSphere 6.0) is that you only need to customize the login page once and it will be available to all other solutions.

UPDATE (03/03/2025) - Customizations for Aria Operations 8.18.x is still applicable, but the login.jsp will need to be updated. (Thanks to Brock Peterson for confirming)

Disclaimer: This is not officially supported by VMware. Please make sure to perform a backup of all original files prior to editing in case you need to restore the system defaults.

vROps (vRealize Operations Manager)

Here are the two locations if you wish to customize the login UI for vROps 6.0. The first is the login.jsp file that controls the login UI. If you wish to simply replace the entire image, it will require some tweaking as the login UI is actually composed of several graphical elements making this task a bit more difficult. The second is the images directory which you will want to upload any content you wish to use for the login UI.

Note: Please make sure to perform a backup of all original files prior to editing in case you need to restore the system defaults.

  • /usr/lib/vmware-vcops/tomcat-web-app/webapps/vcops-web-ent/pages/login.jsp
  • /usr/lib/vmware-vcops/tomcat-web-app/webapps/vcops-web-ent/images

Due to the various tweaks, I have created a sample login.jsp which you can download and reference here. This will allow you to replace the entire background for the vROps login UI as well as adding in some text that you wish to display. I know how big of a fan Rawlinson Rivera is of Justin Bieber, so I thought I use his favorite background for creating what an a custom vROps login UI can potentially look like.

vRLI (vRealize Log Insight)

Here are the two locations if you wish to customize the login UI for vRLI 2.5. The first is the main login background image which is a 600x410 image if you wish to stick with the default layout. The second is a 300x78 transparent image for the vRLI logo, you can either keep this or replace it with your own.

Note: Please make sure to perform a backup of all original files prior to editing in case you need to restore the system defaults.

  • /usr/lib/loginsight/application/3rd_party/apache-tomcat-6.0.36/webapps/ROOT/images/misc/login-bg.png
  • /usr/lib/loginsight/application/3rd_party/apache-tomcat-6.0.36/webapps/ROOT/images/logo/vmware-logo-big-white-v2.png

If you wish to add additional text to the login page, you can edit the following file which controls the login UI.

  • /usr/lib/loginsight/application/3rd_party/apache-tomcat-6.0.36/webapps/ROOT/loginsight/login/login.css

Here is a quick example by inserting the following above Line 20:

<div style="color:#ffffff;text-align:center;font-size:20px">Punching Cloud Edition</div>

Here is an example of what custom login UI for vRLI could potentially look like:

vRA (vRealize Automation)

As a bonus, if you are interested in customizing the Login UI for vRA, be sure to check out fellow Automation colleague Justin Jones who has built this really cool utility called vRA Brand Customizer to help with customizing vRA login UI for the various tenants in your environment. I would recommend keeping an eye on this tool for some really cool stuff coming in the future 😉
