dm-2 | Digital Mappa is a freely available online | Platform As A Service library

I have a simple task to join output from the lsblk command with output from the df command on the field which contains the mount point.

Example output from df:

I need to merge two outputs in Linux. This:

I am trying to recreate the look DM-2 flight software, considering it was written in JS. I am trying to make a countdown clock. But when I go to update the innerHTMl, it spits out NAN, and the function does not repeat. Any clues would be helpful. HTML

I have on a dashboard, a number of panels (numbering around 6)to display data points chart making queries to dockerised instance of PostgreSQL database.

Panels were working fine until very recently, some stop working and report an error like this:

pq: could not resize shared memory segment "/PostgreSQL.2058389254" to 12615680 bytes: No space left on device

Any idea why this? how to work around solving this. Docker container runs on remote host accessed via ssh.

I'm trying to follow this tutorial: https://ivrodriguez.com/installing-self-signed-certificates-on-android/

When I get to the step that tries to remount /system as writeable, I am running into problems. Can someone help me figure out what's wrong? Or what my next troubleshooting steps should be?

Thank you in advance.

Below is what I'm able to see from my basic Linux experience.

i'm pretty new at docker and i try to isolate my python interpreter with some modules but i stuck in the beginning.

I created a simple script like :

I have a dataset with space delimiter in my column "_raw"

I need to extract data from this column into multiple columns

"_raw" column:

We are facing and issue while trying to insert data to influxdb to be picked up from grafana. As of now there a test going on where we are inserting directly from collectd from a host to and influxdb db, the thing is that this is getting pretty huge and this is only information from 1 single host, we have hundreds of hosts in our PROD environment which is our main goal.

What we are trying to do is to insert only the data whenever we need to investigate an outage, for that we are planning to do it from the RAW files that collectd is creating right now. We came across a solution that is there but for NMON which does exactly what we need but for NMON files but I honestly don’t know anything about Golang which is the language they used for that, or at least I think so.

I found in this community that there is a PARSER plugin that is part of telegraf, but what I can’t find is how can I use it to take the information from a RAW file given by collectd and insert it into a influxdb.

I would really appreciate if someone can give me an advice on this matter.

Thanks in Advance.
