How do I revert any customizations

SteveBeauchemin · Post by **SteveBeauchemin** » Tue Jul 18, 2017 11:04 am

I have touched some PHP files in order to make NNA work better for my site.
I would like to start over with a clean install and do the changes one at a time, and fully document what I did.

So, can I simply run the fullinstall over my existing setup? Or do I need to remove NNA and start from scratch.
I would prefer to Not lose my existing flow files.

I just want to get back to an unedited place. Any thoughts on this?

Thanks

Steve B

Backup first, then start from scratch, then restore, then make your documented PHP changes.

Since you are running 2.2.x (assuming the signature is correct), then there is a built-in backup utility and I would suggest using that along with @eloyd's solution.

Let us know if you have any questions!

That's kinda part of the problem... That menu item is broken.

I'll just reinstall from ground zero. I don't mind. I think I broke some file system permissions.

I have really just started getting this into production use.

The Network folks here are just now getting the F5 setup to accept all netflow data. From there they are forwarding it to the NNA setup and wherever else they need to.
I have setup 10 sources to listen on. The F5 is load balancing the flows to all 10 ports. This helps reduce the size of the stored flow files on the NNA disk. Smaller files
means faster reading of the data. At least it does to me.

I have made good headway improving NNA performance. I just need to find a couple more ajax refresh items that kill me. And I have a secret weapon.
I started a project where I can get nfdump to run parallel processes. Something that actually works. When I run top and look at nfdump in NNA, I used to see
only one process running 100% of One CPU. Now I see many processes and the screens come back much faster. I'll share this stuff as soon as I get a clean NNA install
in place again. Then I can run through the install steps and share how I did it. It is nice to see nfdump use all the CPU in a system, and I have 8.

Thanks. You can close this.

Just read the scripts for Backup and Restore found in /usr/local/nagiosna/scripts

I think Eric's suggestion looks like a good one. The backup only backs up non Application data. That is exactly what I need. Then Install clean, and restore.

I'll take that route.

Thanks

May we go ahead and close this topic?

SteveBeauchemin · Post by **SteveBeauchemin** » Tue Jul 18, 2017 7:03 pm

Yes, please close this. I have uninstalled and reinstalled. Not as simple as it sounds.

Used these steps

Code: Select all

mysql -uroot -p[password]
drop database nagiosna;
exit

systemctl disable httpd
systemctl stop httpd
systemctl disable nagiosna
systemctl stop nagiosna
systemctl disable mariadb
systemctl stop mariadb

rm -rf /usr/local/nagiosna
rm -rf /var/www/html/nagiosna
rm -f /var/www/html/nna.php

yum -y remove wkhtmltox

rm -rf /tmp/nagiosna

cd /tmp
tar -xzvf nagiosna-2.2.3.tar.gz

cd /tmp/nagiosna

either edit fullinstall and 
  run_steps prereqs sourceguardian timezone rrdtool build_nfdump library_path nagiosna backend db firewall selinux install_mibs 
install_sudo install_cron wkhtmltopdf webroot daemons

remove firewall from the list
remove install_sudo from the list

or

cd /tmp/nagiosna
touch installed.build_nfdump
touch installed.firewall
touch installed.install_sudo

After that, I was able to install again.

The restore script is written for RH 6 so was not good. It refers to mysqld and not mariadb.
There were also many errors related to iptables when I ran the restore.

But, I have a clean install again. Seems to me that there should be an uninstall script included.

Thanks... I think. Please close this.

Generally speaking, Nagios software is intended to be installed on a machine which serves (and will never serve) any other purpose. So an uninstall procedure is likely considered unnecessary. "Why uninstall something from a machine which serves no other purpose? If you're giving it another purpose, then install that purpose from scratch" is the logic.

I figured you would start with a new, fresh Linux install and reinstall NNA from there, then do the restore. Didn't expect you to try to find all the pieces that need to be uninstalled first.

Steve,

I'd like to see the nfdump stuff as soon as you have a chance - even if it isn't refined it would be cool!

Thanks!

Brian,

The concept works good. If you run individual nfdump commands. Instead of seeing one nfdump command in 'top' using 100% of one CPU, I see many nfdump commands on many CPU using 50% or less CPU. So I am encouraged.

I suspect it would be better if the native python code that runs NNA did what the wrapper is trying to do. All I am doing is taking one BIG job, and making it into many small jobs. Then I use GNU Parallel to fire off all the small jobs to all the CPU. I think perl can spawn off separate jobs with their own PID, and rejoin the initial perl program when they finish. So GNU Parallel is not mandatory, just convenient.

This is all still make believe, in development, but look for me SteveBeauchemin on Github and you can clone the perl file. If you read the code, it should give you an idea of what I am doing. There are just some things I need to work around. Like Top Talkers. I don't know how to make those queries into smaller pieces. And the Chord diagrams that we all love, if you run 4 at the same time like one of the basic screens does, well... I am having difficulties there. But I just started to tinker and it is all new. And fun.

I just got NNA repaired and back to normal today. Yes, I broke it, then fixed it. So I am starting to play with nfdump again to see which actual NNA items work properly with the wrapper. I think I need the newer version of nfdump too, as I did reload and got it reverted to 1.6.13, and am now seeing errors that I did not have when I ran nfdump v1.6.15.

You know, I'm not a real programmer, I just play one here on Earth...

We can go PM if that makes sense. I'd like to have feedback. I think what I did so far is trivial for a real programmer. Once the concept is understood, and the nfdump parameters are explored. If you grok what I am doing to make this work, and can get it built into the native NNA, I'll wait for the new version.

But, other than complain about how slow stuff is, I prefer to poke the beast and see what I can do to make things better. I think you may have noticed that huh.

Let me know what you think.

Steve B

I am including in code brackets below all the changes I have made to the NNA stuff so far. (not the Nagios XI component though)
It makes NNA usable for me. Without these changes, not much fun... this makes NNA useful without nfdump wrapper.
Some stuff will still take forever to run and that is why I had the wrapper idea.

Code: Select all

Disable some automatic run of reports.

When clicking a menu to get to the reports tab, the currently selected item 
will automatically run before you have a chance to change the menu item to 
the report you actually want to see.

This change will change the default such that you need to click the run button.

vi /var/www/html/nagiosna/application/views/generic/reports.php

Change in vicinity of Line 33

    // var run_change = true;
    // SLB 2017-07-06 stop page from running automatically.
    var run_change = false;

When selecting a Report - do not run simply because I chose it. What if I 
missed by one item, and wanted the next one down the list. Only run once 
the Run Report button is clicked.

Change in vicinnity of line 157

    // var run_change = true;
    // SLB 2017-07-10 stop page from running automatically.
    run_change = false;

Caveat: When you do click the Run Report button, there is no indication that 
the tool is trying to populate new data. The previous screen stays in place 
until replaced by new content, no spinner, no indicator of work in progress. 
The header changes but the table data does not. It is confusing and makes you 
think it has the new data present.


Changes to add more time interval choices

The smallest window by default is 24 hours. These changes below 
add in 2, 4, 6, and 12 hour choices for queries. You can always 
use a custom time frame, but these are now available, and the default 
is changed from 24 hours to 2 hours. This default change helps performance.
