Monitoring Linux (CentOS) Hosts

I'm using PRTG as my main monitoring solution. This may sound simplistic but there doesn't seem to be an easy built in way to monitor everything "bad" on a Linux host including

  • Degraded RAID (software RAID)
  • Failing RAM
  • Failure of postgres to replicate
  • Common environmental such as high load, low memory, full disk
  • Incrementing counts of random 'errors' in VLM.

mongodb 3.2 cluster database compatibility to mongodb 5.0
cn flag

We have a mongodb 3.2 production cluster that we need to upgrade to mongodb 5.0.

Instead of upgrading in place, we are considering creating a new mongodb 5.0 cluster, export the DB from 3.2, and import the DB into the mongodb 5.0 cluster.

Will there be any issues with upgrading this way? What we are uncertain about is whether the database format has changed from version 3.2 to 5.0, and whether the d ...

Keep SSH connected until command output completes
us flag

I am trying to setup a Nagios rule that runs an SSH command and outputs the contents to a file. The issue I believe I am running into is that SSH runs the command and closes the connection before the output writes to the file. If I run the script manually from the CLI it works great, but from within Nagios it is writing 0 size files. One file I checked just included the header of the output which lea ...

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
