Hi,
Is there a way for me as admin to see how many resources each user/site is using (RAM/CPU/etc...)?
Couldn't find a page with such info.
TIA.
-
Well per site is not possible but all over you can see in GUi. You have to perform below installation
http://forum.centos-webpanel.com/how-to/(tutorial)-installing-netdata-on-centos-web-panel/
Check demo before installing it into your server

Unfortunately, it resulted in an error, quite early.
Right after the command pip install mysqlclient
I was getting these errors:

I guess I shouldn't continue the installation...
Any idea what's wrong?

Does this helps
yum install python-devel -y

yum install python-devel -y
Yes, it does. Thanks!
BUT... then I get this error:
[root@cwp netdata]# rpm -ivh https://github.com/firehol/packages/releases/download/2018-08-19-1732/firehol-3.1.6-1.el7.noarch.rpm
Retrieving https://github.com/firehol/packages/releases/download/2018-08-19-1732/firehol-3.1.6-1.el7.noarch.rpm
error: Failed dependencies:
ipset is needed by firehol-3.1.6-1.el7.noarch
So I can't write the file /etc/firehol/fireqos.conf
-
Ok, figured it out after some search.
You first have to run this:
[codee]yum install ipset-service
Now it works. Thanks!
I'll go and check this. Looks great.
-
Ok, this DOES look impressive and lots of data (too much? :) )...
Coming back to my original question - how can I see resources used by a specific site.
Let's say there's a huge increase in CPU usage - how can I tell which site is causing it and which process in this site?
-
Oh, and one more thing - I see this system is open for all. How can I protect its access with a password so others won't use it?
-
I got to work now, and am trying to access netdata from my workplace's PC, and get this:
Access to file is not permitted: /usr/local/apache/htdocs/netdata/usr/share/netdata/web//index.html
Is it related at all to the fact I'm trying to access it from another PC?
I've also tried from my mobile, and got the same.
Any idea what's wrong?
-
Well you cannot monitor per site basis. Its for those who who to see how their server is functioning and using resources based on GUI. This send notification too on desktop to let user know if something is wrong.
Well that error is related to permission I think
Did you try to run the following command for permission
chown -R netdata:netdata /usr/local/apache/htdocs/netdata
-
Did you try to run the following command for permission
chown -R netdata:netdata /usr/local/apache/htdocs/netdata
Wow you're a savior! Thank you!
Wasn't it part of the tutorial, though? I can swear there was such a command in there...
-
You can actually password protect it using /usr/local/apache/bin/htpasswd and adding it in vhost file.
Search online to know how.
Well there was command in tutorial but I don't know why it didn't execute.
-
Sorry for so many questions...
What if I won't password protect it. Is there any vulnerability in leaving it open to all?
Do you protect yours?
-
Yes we do password protect it. Obviously its not good to keep it open. anyone can come and change settings see things. Thats not a vulnerability but why would I allow someone to see my chart :)
-
Correct. I will have to investigate how to do it. As a newbie, everything looks so difficult (throws me back to the MS-DOS days before the Windows era, but I haven't used command line ever since)...
Any chance you have a guide up your sleeve to share how to put this password protection in place?
-
Did you try to run the following command for permission
chown -R netdata:netdata /usr/local/apache/htdocs/netdata
Thanks for the fix Bullten
-
Thanks for the fix Bullten
So it's not only me...
-
Well you can password protect it like below
nano /usr/local/apache/htdocs/netdata/etc/netdata/netdata.conf
Find # bind to = under [web] and uncomment it and change it to bind to = localhost
Before
[web]
# mode = static-threaded
# listen backlog = 4096
# default port = 19999
# bind to =
# web files owner = netdata
# web files group = netdata
After
[web]
# mode = static-threaded
# listen backlog = 4096
# default port = 19999
bind to = localhost
# web files owner = netdata
# web files group = netdata
Create Password
ln -s /usr/local/apache/bin/htpasswd /usr/sbin/htpasswd
htpasswd -bc /usr/local/apache/htdocs/netdata/usr/share/netdata/web/.htpasswd yourusername yourpassword
Copy and Paste all lines not one by one
cat > /usr/local/apache/conf.d/netdata-auth.conf << "EOF"
<VirtualHost *:80>
RewriteEngine On
ProxyRequests Off
ProxyPreserveHost On
<Proxy *>
Require all granted
</Proxy>
# Local netdata server accessed with '/netdata/', at localhost:19999
ProxyPass "/netdata/" "http://localhost:19999/" connectiontimeout=5 timeout=30 keepalive=on
ProxyPassReverse "/netdata/" "http://localhost:19999/"
# if the user did not give the trailing /, add it
# for HTTP (if the virtualhost is HTTP, use this)
RewriteRule ^/netdata$ http://%{HTTP_HOST}/netdata/ [L,R=301]
# for HTTPS (if the virtualhost is HTTPS, use this)
#RewriteRule ^/netdata$ https://%{HTTP_HOST}/netdata/ [L,R=301]
<Location /netdata/>
AuthType Basic
AuthName "Protected site"
AuthUserFile /usr/local/apache/htdocs/netdata/usr/share/netdata/web/.htpasswd
Require valid-user
Order deny,allow
Allow from all
</Location>
</VirtualHost>
EOF
Restart Apache
service httpd restart
Note: Now you cant access netdata using port you need to access like http://yourserverip/netdata/
-
Create Password
ln -s /usr/local/apache/bin/htpasswd /usr/sbin/htpasswd
htpasswd -bc /usr/local/apache/htdocs/netdata/usr/share/netdata/web/.htpasswd yourusername yourpassword
First, thank you so much for all your help.
Second, I got the following error:
[root@cwp ~]# ln -s /usr/local/apache/bin/htpasswd /usr/sbin/htpasswd
ln: failed to create symbolic link ‘/usr/sbin/htpasswd’: File exists
-
Its just a warning to let you know file already exist there. You dont need to worry about that. I would suggest you to follow this tutorial

Hey Bullten,
I followed all on your write up for adding password protection and it all worked fine except for some reason I had to use chown -R netdata:netdata /usr/local/apache/htdocs/netdata again to access it after filling in user and password. I had to use chown -R netdata:netdata /usr/local/apache/htdocs/netdata yesterday in order to access netdata. What would cause me to have to do it today?
Or is this fixed now that I added password protection?
Thanks, Rug3r
-
nano /usr/local/apache/htdocs/netdata/etc/netdata/netdata.conf
Find
# run as user = netdata
# web files owner = netdata
# web files group = netdata
Uncomment them
run as user = netdata
web files owner = netdata
web files group = netdata
Save and restart netdata
service netdata restart
See if its happening now.

I only managed to break my nginx when adding things to nginx.conf :(
As I can't password protect it, I think I'll have to uninstall it unfortunately...
