Qwiklabs – GCP Essentials – Creating a Virtual Machine stuck on 10/15 points

I was using Qwiklabs to learn a bit about Google Cloud Platform (GCP) and started the GCP Essential quest.
During the 1st lab (Creating a Virtual Machine) I got stuck on 10/15 points, despite the fact that I thought I’ve completed all the steps as required.

Understanding Elastic Heartbeat time metrics – ICMP

I wanted to play a little with Grafana while having Elasticsearch as a back-end and decided to use Elastic Heartbeat as my data generator. It’s an easy, no fuss, to set up the Heartbeat itself as well as the first Heartbeat HTTP monitor, but when I saw all the available Heartbeat time metrics for the HTTP monitor I got a bit overwhelmed. So decided to to gradually progress from ICMP through TCP and finally to HTTP Heartbeat monitors and that the way this post is going to evolve as well:
  • Part 1 – Elasticsearch Heartbeat ICMP time metrics
  • Part 2 – Elasticsearch Heartbeat TCP time metrics (work in progress)
  • Part 3 – Elasticsearch Heartbeat HTTP time metrics (work in progress)

Use jmxsh – JMX CLI tool – to troubleshoot remote JMX RMI connection

Overview

Occasionally when creating SiteScope JMX monitors  you might want to verify connectivity or to troubleshoot remote JMX RMi connection. You might also want to be able to provide a tool to the (monitored target) Java application team to try the connectivity locally on the target  server.

jmxsh is a command line utility that allows you to connect to (local or remote) JMX and browse the counters. Continue reading Use jmxsh – JMX CLI tool – to troubleshoot remote JMX RMI connection

How to copy PuTTY SSH Hosts Keys between different users/machines on Windows

SiteScope to Slack Alerts Integration

Intro

I was recently introduced to Slack by a friend of mine and found it to be quite awesome (especially if the organization that you are working in doesn’t block their site). It allows you to have all of the communication in the organization to be in one place. So I thought: “If that’s the place where all the communication goes, SiteScope should send it’s alerts there as well”. That’s how this SiteScope to Slack Alerts Integration idea was born.

HP BSM Connector fails to load policies list into UI with “Error parsing XML” exception

 The issue

On a bright sunny day, without any prior warning (as it usually happens in DEV environment) our HP BSM Connector decided that it doesn’t want to show any policies in the UI and instead to present me with “An unexpected error occurred” kind of message:

Unexpected error
BSM Connector Unexpected error.

This post is one in a series of articles that are aimed for HP BSM guys (and rarely girls) that are new to the, let’s call it “legacy”, Operations Manager and its agents. One of the new doctrines is the pattern matching syntax that is used in OA policies and which now have become part of BSM Connector policies.
