I cannot view the URL pattern chart on my overview page.
I have already set up the URL Pattern configuration in /etc/netdata/go.d/web_log.conf and restarted the deamon but it still doesn’t show up.
Hi, @GeorgiaTs. The answer is on the screenshot (see “url_patterns” syntax).
Do you want me to help to convert from “categories” (python version) to “url_patterns” (go version)?
Hi, @ilyam8
Yes, can you help to convert from “categories” (python version) to “url_patterns” (go version).
@ilyam8 These are my “categories”.
apache_netdata: # name the charts
path: ‘/var/log/apache2/access.log’ # web server log file
categories:
SW : ‘^/home/home1’
contact : ‘^/sw/home/contact’
about : ‘^/sw/home/about’
portal : ‘^/sw/home/portal’
Can you convert it from “categories” to “url_patterns”.
@Sharvin_Koli just to make sure you are using the go version. Is the file ‘/etc/netdata/go.d/web_log.conf’ or ‘/etc/netdata/python.d/web_log.conf’?
@ilyam8 Yes, I am using go version and my web_log.conf file is in ‘/etc/netdata/go.d/web_log.conf’ .
Is this right syntax to get url patterns in go.d version. But after inserting this syntax in web_log.conf i am not getting web log charts.
What might be problem? Is there any other configuration to deal with?
@Sharvin_Koli the problem is invalid syntax (you will see it if running the plugin in the debug mode)
[ ERROR ] web_log[nginx] weblog.go:85 init failed: create pattern {Name:sw Match:^/home/home1}: invalid syntax
Try the following, it should work
# go.d/web_log.conf
jobs:
- name: apache_netdata
path: '/var/log/apache2/access.log'
url_patterns:
- name: sw
match: '* /home/home1*'
- name: contact
match: '* /sw/home/contact*'
- name: about
match: '* /sw/home/about*'
- name: portal
match: '* /sw/home/about*'
Great!
Basically, it is ‘matcher_type pattern’. '* /home/home1*' means:
- use glob matcher (‘*’).
- match everything that starts with ‘/home/home1’.
These are the charts we create for every endpoint (URL pattern):
- Responses By Status Code in responses/s
- Requests By HTTP Method in requests/s
- Bandwidth in kilobits/s
- Request Processing Time in milliseconds
