HPE SSD Slow performance

We are facing a extremely slow server. We are using SSD RAID 6 but cannot seem to find the cause why.

Memory is 64GB

RAID 6 SSD HPE Disks

HPE vMware 7.X

It's my first post - if I missed something, apologies ...

When I execute a script in crontab the output is in a different language
in flag

I am executing a script in a crontab that writes a log, when I run it as root, the log is written in spanish.

But when I run it in the crontab, the output is in english.

Is there a way to run the crontab with the same configuration I do when I run it as root?

Chronyc equivalent for ntpdate -q
it flag

According to ntpdate and chronyd man pages

In ntpdate -q : Query only - don't set the clock.

chronyd -q : When run in this mode, chronyd will set the system clock once and exit. It will not detach from the terminal.

Is there any alternative command in chronyc to the following command, "query only without setting the clock"?

Can windows DNS server be configured to return a fully qualified DNS alias?
mr flag

Problem

We have a 3rd party web app installed on a windows server. There is an alias DNS record setup so that user can type in to a web browser the app name i.e. "testapp" and get the site. This works well in Chrome browser but does not work as well with Edge Chromium browser. Edge Chromium does not see the web app as a local server so does not trust it to send domain credentials.

Azure VMs, Monitoring and Load Balancing

I have two Windows VMs behind a load balancer with monitoring setup on both VMs. When checking the CPU utilization, I notice that the load isn't evenly balanced. Here's what I'm seeing. Does this look normal for a 24 hour period? When checking for a shorter time period, it seems like the balancing isn't even.

These are Standard B2s VMs. They're hosting an API. Looking at the most recent server re ...

HAProxy - http log and TTFB discrepency

I am noticing a large discrepancy between TTFB in my browser networking tool and the HAProxy logs. HAProxy will say the request returned in 29 ms for example, but the browser reports anywhere from 50-600ms. I'm noticing this when traffic is the heaviest. The HAProxy server has 8 cores and 1gb networking connection on bare metal so I do not think its a limitation of the machine, but instead tuning that I ...

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.
