Predicting multiple metrics in Splunk
Splunk has a
predict command that can be used to predict a future value of a metric based on historical values. This is not a Machine Learning or an Artificial Intelligence functionality, but a plain-old-statistical analysis.
So if we have a single metric, based on historical results we can produce a nice prediction for the future (of definable span), but predicting multiple metrics in Splunk might not be as straightforward.Continue reading Predicting multiple metrics in Splunk

How to collect StatsD metrics from rippled server using Splunk
The XRP Ledger (XRPL) is a decentralized, public blockchain and rippled server software (rippled in future references) powers the blockchain. rippled follows the peer-to-peer network, processes transactions, and maintains some ledger history.
rippled is capable of sending its telemetry data using StatsD protocol to 3rd party systems like Splunk.Continue reading How to collect StatsD metrics from rippled server using Splunk
Plotting Splunk with the same metric and dimension names shows NULL
When you try plotting on a graph Splunk metric split by a dimension with the same name (as the metric itself) will show NULL instead of the dimension.Continue reading Plotting Splunk with the same metric and dimension names shows NULL
How to use an SSH key stored in Azure Key Vault while building Azure Linux VMs using Terraform
So I want to use the same SSH Public key to be able to authenticate across multiple Linux VMs that I’m building in Azure in Terraform. While I did find a lot of examples (including among Terraform example repo) of how to do it if you have the key stored on your local machine I couldn’t find (or didn’t search long enough) how to use an SSH key stored in Azure Key Vault while building Azure Linux VMs using Terraform.Continue reading How to use an SSH key stored in Azure Key Vault while building Azure Linux VMs using Terraform

Choosing a Cloud Provider for a Bootstrapped StartUp
There are many different options for Funded start-ps to get free credits from various cloud providers, but choosing a cloud provider for a Bootstrapped startup is a bit harder.
Some might have already a preference towards one cloud provider over another (based on their experience or other factors), but here I’m trying to compare them from a pure “free cloud provider credits for a bootstrapped startup” perspective,Continue reading Choosing a Cloud Provider for a Bootstrapped StartUp
Create a Random Bit Set with Jinja
Once in a while, when working with Jinja templating engine, you might need to create a random Bit Set with Jinja. Some might also call it a Binary Flag Set.
Basically, this will be a binary number (for example
10110) where each digit (bit) represents whether something is on/enabled/present or off.
In some systems, this binary number is actually stored as a base 10 integer. So
10110 will be stored as
