WEBVTT 00:00.180 --> 00:02.670 OK, so now let's create our first data source. 00:02.820 --> 00:06.240 The first task is going to be the test data DB data source. 00:06.390 --> 00:10.620 The purpose of this data source is for learning about total fake data. 00:10.890 --> 00:17.550 OK, so one point about Bafana Bafana allows you to query, visualize, alert on and understand your 00:17.550 --> 00:19.440 metrics no matter where they are stored. 00:19.620 --> 00:24.000 OK, so stored, OK, data is not stored in Crafar. 00:24.060 --> 00:31.440 Instead, you create data sources in your Fatah, which acts like query adapters, which query data 00:31.440 --> 00:35.250 that exists in the underlying system where the data is stored. 00:35.280 --> 00:42.360 For example, an SQL server via another interface that can read log files via Prometheus, which can 00:42.360 --> 00:45.970 raid many other types of data stored in various other systems. 00:45.990 --> 00:51.270 Some of the Blocks DB signed with Xbox and lasting search, so the data that you're querying is still 00:51.270 --> 00:54.950 stored in the underlying system, no matter what that is. 00:54.960 --> 01:00.120 But in Gryffindor, you create things called data sources, which are query adapters that will request 01:00.120 --> 01:03.280 data from the underlying system, whatever that is. 01:03.300 --> 01:08.640 So the first data source will create in Gravano is the test DB data source, and this is all just fake 01:08.640 --> 01:10.920 data that is created randomly in real time. 01:11.070 --> 01:16.890 OK, so back into Safana on this menu, on the left here, down the left, this gear icon configuration 01:16.890 --> 01:19.500 data sources and data source. 01:19.950 --> 01:27.360 And if we scroll all the way to the bottom, select test data DB side, press that whole square. 01:27.390 --> 01:30.710 You can rename it to anything you like, but that name is perfect. 01:30.720 --> 01:37.410 We can save and test and this data source updated data sources working excellent here in the dashboards 01:37.410 --> 01:43.520 section, we get a default dashboard that we can import, so we'll import that OK. 01:43.530 --> 01:50.010 And in setup, we can visit the actual GitHub repository where the source code is stored if you want. 01:50.610 --> 01:52.110 And that's what it looks like. 01:52.970 --> 01:53.790 But we don't need that. 01:53.800 --> 01:54.900 You can look at that if you want to. 01:54.960 --> 02:01.680 OK, so that data sources now set up, if we now go to that icon, their dashboards manage down here. 02:01.710 --> 02:04.290 There's a new one simple streaming example. 02:04.290 --> 02:06.060 We can click that to view it. 02:06.180 --> 02:09.750 OK, so this is the test data DB data source. 02:09.750 --> 02:13.340 Just a very simple dashboard that we can experiment with. 02:13.350 --> 02:16.470 You can quickly just press the buttons on it to see what they do if you like. 02:16.470 --> 02:19.750 It doesn't matter if you break anything, we can always fix it up. 02:19.800 --> 02:25.920 So, for example, if I move things around and I try to exit, you will ask me if I want to say the 02:25.920 --> 02:26.460 dashboard. 02:26.460 --> 02:28.850 So let's say I did want set dashboard. 02:28.860 --> 02:29.390 I can press. 02:29.400 --> 02:35.640 Yes, I can add my notes if I want press save and I can choose whether I'm saving as a new dashboard 02:35.640 --> 02:39.120 or overwriting the existing let's just say I overwrite existing dashboard. 02:39.210 --> 02:44.520 OK, so the dashboard is saved and it's been overwritten as a matter if we go back to dashboards harm 02:44.520 --> 02:49.680 down the bottom here, it shows my most recently viewed dashboard and that's how it was when I saved 02:49.680 --> 02:49.850 it. 02:49.860 --> 02:54.270 But if I decided I didn't like it that way and I wanted to go back to the way it was originally, I 02:54.270 --> 02:54.720 could go. 02:54.780 --> 03:01.470 Configuration data sources go back into that dashboards and press re-import, and that will put it back 03:01.470 --> 03:03.060 to the way it was at the beginning. 03:03.060 --> 03:05.310 So if you break the dashboard, it doesn't matter. 03:05.370 --> 03:05.760 Excellent. 03:05.790 --> 03:11.280 So going back to dashboard time now because I've recently viewed a dashboard is showing up down here. 03:11.280 --> 03:15.740 So simple streaming example that's back to the way it was when I first viewed it the first time. 03:15.750 --> 03:16.170 So excellent. 03:16.170 --> 03:21.060 So feel free to just press the buttons, but it doesn't really matter will go into the more details 03:21.060 --> 03:22.900 as we progress the next few videos. 03:22.920 --> 03:23.370 Excellent.
