klogg VS LibreNMS

I'd love to see a tool that lets you modify large files efficiently.

I had to replace line 4 of a 200 GB SQL dump, it took a substantial amount of compute time to perform a find / replace with sed and it also required having over double the disk space since sed creates a temp file before it writes out the new file.

Using a hex editor could have worked but it seemed too risky because data integrity was really important.

There's also some other scenarios where maybe you have a massive file and the tool that's using it (such as a SQL import) throws an error on line 1,025,421. Trying to find what the contents of that line is on the command line could be time consuming if you need to read in the whole file. For read operations I know there's a few graphical tools like https://github.com/variar/klogg that efficiently let you scan, search and jump to points in a file quickly but I haven't found a good one on the command line.

reminds me a bit of klogg https://github.com/variar/klogg which is more for log files and based off glogg which went dead. it has nice filtering and highlighting type stuff. It's great for live views of log files.

glogg / klogg

For anybody who goes through this hell, I highly recommend [Klogg](https://github.com/variar/klogg).

For example, the file star2002-full.csv from https://sdm.lbl.gov/fastbit/data/samples.html is a 1.99GB file and it takes less than 10 seconds to load in Notepad+. It's almost instant in https://github.com/variar/klogg.

Bug report is over here

I playing with LibreNMS in my lab, just for the heck of it.

git clone https://github.com/librenms/librenms.git

LibreNMS is awesome! It's a fork of Observium, but has a more "friendly" development philosophy—there's some history there.

- NMS / NPM: NetXMS, Zabbix, LibreNMS, PRTG - NCM, updates, automation: Unimus - IaC / automation: Ansible - DCIM / IPAM: NetBox - IPAM / DDI: Infoblox

However, you can try your luck with a more "all-in-one" like LibreNMS that includes a lot of stuff and quite an amount of integrations (like sflow, snmp, checkmk, etc...) which is probably what you're looking (the all in a single screen)

take a look at snmp and librenms https://www.librenms.org/ I have been using this for years and it has never let me down. You can even then import data into Grafana if you want.
