In this video we'll walk through exercise one step by step. The first step is to log
into your virtual environment. For these exercises we'll be using the PI client
01 machine and the user PI School student 01 along with the password you were given.
Once we're logged in we can open up Google Chrome and navigate to the PI Web API home
page. Generally this will be the name of the PI Web API server either hostname or
fqdn followed by a forward slash PI Web API. From this home page we can
see a link to the help documentation that is hosted internally within the PI Web API.
The same information can also be found online at our techsupport.osisoft.com site.
Let's see how we can navigate through the PI Web API using the links provided from the home page.
If we click on the system link it takes us to a page with some different information about the PI
Web API itself. We can follow the user info link to see which account we are authenticating as and
we see that the PI Web API has indeed identified our PI school student 01 account. Observe that at
the top of the page we are given links to specific help pages for the endpoint that we are at.
If we go back to the system default end point we can click the status link and see more
information about the PI Web API including how long it has been running since startup.
From the homepage we can click on the data server link which takes us to a list of the
known PI data archives. Click the points link under the data server PISRV01. If we use CTRL-F
and search for the tag name sinusoid we can find the description of the tag .
The self link takes us to an endpoint specifically for this PI tag. Click on the
attributes link and we see the point configuration attributes including the compression deviation.
Now use the hyperlinks to navigate back up the hierarchy to PISRV01
by clicking on the point link and then the data server link.
Back at the home page we can navigate to AF data as well by clicking on asset servers.
Click the databases link under AF server PISRV01, click the elements link for the NuGreen database.
We can see the root elements and navigate down the hierarchy by clicking the elements links.
Click the value link to show the attribute values for the b210 element
and we can see the value for the b210 fuel savings attribute here. Outside of
the browser let's take a quick look at the AF configuration database for PI Web API.
Open PI System Explorer and navigate to the configuration database.
We can drill down to find the PI Web API element for PISRV01.
If we click on the system configuration element for this instance we see
configuration attributes for our PI Web API, for example we can look at the authentication
methods attribute which controls the protocols that PI Web API allows for
authentication. For our instance we see that both basic and Kerberos are enabled.
