WEBVTT 00:00.590 --> 00:07.670 In the last lecture we were talking about the basics of Nginx logging as well as we had an overview 00:07.670 --> 00:11.120 about the basics of Nginx access logs. 00:11.510 --> 00:13.640 So we'll continue with that. 00:13.640 --> 00:20.900 And in this video we'll have our own custom format for the logging facility as well as access log is 00:20.900 --> 00:21.530 concerned. 00:22.820 --> 00:25.150 So let's go to the Nginx logs. 00:26.200 --> 00:27.970 Or the Nginx configuration. 00:30.980 --> 00:31.370 I know. 00:31.450 --> 00:32.530 Nginx.conf. 00:34.220 --> 00:40.340 And before we go ahead, I just wanted to show you one more directive, which is access underscore log. 00:40.400 --> 00:48.770 So followed by the access underscore log is the file system location in which the log will be stored. 00:48.770 --> 00:49.970 So currently it is. 00:50.000 --> 00:52.100 Var log nginx access dot log. 00:52.100 --> 00:55.730 So this is something that you can change according to your environment. 00:56.510 --> 00:57.890 And one more. 00:59.140 --> 01:01.570 Directive which was present is the main. 01:01.570 --> 01:05.020 So the mean corresponds to the log format. 01:05.050 --> 01:06.040 Context. 01:06.190 --> 01:13.930 So if we have multiple log format sections, then we can actually mention the sections over here. 01:14.620 --> 01:18.310 So let's define one more context for the log format. 01:18.460 --> 01:21.670 So I'll say log underscore format. 01:27.040 --> 01:28.360 I'll name it master. 01:28.600 --> 01:34.750 And for this type of logs, I just need remote ADR. 01:37.180 --> 01:39.050 Followed by the status code. 01:39.070 --> 01:40.060 So I'll say. 01:44.050 --> 01:45.040 And. 01:46.490 --> 01:47.450 I'll change the. 01:48.500 --> 01:50.510 Context from main to master. 01:51.140 --> 01:53.780 So now the access log will be. 01:54.860 --> 02:00.200 Storing only two variables which are mentioned in the master context. 02:00.590 --> 02:02.360 So let me save the file. 02:02.390 --> 02:06.740 Let's check if everything is proper and let's reload the nginx. 02:09.570 --> 02:12.120 Okay, So go into that. 02:14.240 --> 02:14.510 Deal. 02:16.180 --> 02:18.790 Let's try to open example.com. 02:18.950 --> 02:19.810 I see jpeg. 02:22.050 --> 02:25.790 And it seems to be the cash. 02:25.800 --> 02:26.850 So let's. 02:28.920 --> 02:30.630 Do my seed one dot jpeg. 02:31.720 --> 02:33.100 And let's reload it. 02:35.540 --> 02:43.190 And now you see the format in which the log has been started to store is different. 02:43.220 --> 02:48.860 So here it is only showing the IP address of the client, followed by the response code. 02:48.860 --> 02:54.710 So first is 304 and second is 200, which directly corresponds to the. 02:56.220 --> 02:59.880 Format which we had written in the Nginx configuration file. 03:00.450 --> 03:07.410 So coming back to the Nginx.conf, so this is the format in which the access logs are stored. 03:08.830 --> 03:15.400 Now, one of the downsides of mentioning the format over here is that it is a global directive. 03:15.700 --> 03:23.620 So if you have multiple websites on a single server, all the website will start to store according 03:23.650 --> 03:26.560 to the master context. 03:26.830 --> 03:34.870 So what we if we want that website, one should store logs in the main format and website two should 03:34.870 --> 03:37.420 actually store logs based on master format. 03:37.450 --> 03:41.410 So this is a flexibility which nginx allows us to do. 03:41.440 --> 03:48.000 So we can actually specify this in the virtualhost configuration. 03:48.010 --> 03:50.380 So if I go to conf debconf. 03:51.490 --> 03:53.410 So below the server directive. 03:54.070 --> 03:56.230 If I mentioned access underscore log. 03:59.310 --> 04:01.980 I can also specify the custom location. 04:01.980 --> 04:09.510 So here if I say var log nginx example dot log followed by the context that we want. 04:09.540 --> 04:10.590 So I'll say main. 04:12.920 --> 04:17.390 And I'll verify and let's do a reload. 04:20.000 --> 04:20.420 Okay. 04:21.710 --> 04:24.740 So let me refresh the page. 04:26.960 --> 04:35.270 And now if you go to Var log Nginx, now you see there is a third file, which is example dot log which 04:35.270 --> 04:35.780 is stored. 04:36.470 --> 04:42.950 So if I do a less on example dot log here you will see the example. 04:42.950 --> 04:50.060 Dot log is actually storing the log in the format of main. 04:50.450 --> 04:53.000 Now let's close this. 04:54.110 --> 04:55.520 And let's modify. 04:59.430 --> 05:02.100 The webcomic again. 05:06.590 --> 05:12.860 Nginx conf debconf and let's modify it to master. 05:15.100 --> 05:16.800 The three road links. 05:18.740 --> 05:19.850 Let's do a tale. 05:23.870 --> 05:24.470 Sorry. 05:26.990 --> 05:28.670 On example log. 05:31.520 --> 05:35.060 Let's refresh the page from the browser. 05:35.630 --> 05:38.930 And now you see it is following the master format again. 05:39.500 --> 05:44.540 So this is the flexibility which Nginx allows us to give. 05:44.750 --> 05:48.870 First of all, we can define our own log format. 05:48.890 --> 05:55.130 It can be either global or it can even be a specific to a particular server location. 05:55.730 --> 05:57.710 So this is it about. 05:58.740 --> 06:00.260 The access logs. 06:00.270 --> 06:04.050 I hope this has been informative for you and I'd like to thank.
