Q: I do not see my service in the `directory of services <https://stats.perfsonar.net>`_, where is it?
**A:** Much like DNS, the information that will populate the Lookup Service will take time to propagate. Please allow some time (e.g. a few hours) before your service will be fully visible. If it stil does not appear, you may want to look in :ref:`lsregistrationdaemon.log <config_files-lsreg-logs-primary>` for errors.

Interacting with this service can be done by scanning the map to find an instance where you may know a location, or by trying to search on specific terms.
12
-
13
-
As an example, a search for "es.net" will return hosts that have that domain:
14
-
15
-
.. image:: images/directory-search.png
16
-
17
-
Clicking on a host will bring up specific information about the software and hardware:
18
-
19
-
.. image:: images/directory-host.png
20
-
21
-
Searching the map after narrowing the results will place specific red beacons for each host.
22
-
Zooming into a region that has a larger red beacon will show where individual nodes are located:
23
-
24
-
.. image:: images/directory-map.png
25
-
26
-
Note that map functionality relies on accurate latitude and longitude information, that is entered when the machine is configured. Machines that have inaccurate information will not be placed correctly.

perfSONAR Lookup Service

------------------------
31
-
32
-
You can also query perfSONAR's *Simple Lookup Service* (sLS) directly.
33
-
34
-
There is a Python client available for the sLS that offers basic query functionality.
35
-
The sLS client comes with two wrapper functions:
36
-
37
-
- find_ps_ma - a command line script that returns a list of MAs that have test results for given host.
38
-
- sls_dig - a script that is similar to "dig" tool. It retrieves information about a host registered in the sLS.
39
-
40
-
These can be installed via easy_install::
41
-
42
-
easy_install sls-client
43
-
44
-
Or via: https://pypi.python.org/simple/sls-client/
