6 Setting Up the environment
7 --------------------------
9 To setup and run the TSDR data store ElasticSearch feature, you need to have
10 an ElasticSearch node (or a cluster of such nodes) running. You can use a
11 customized ElasticSearch docker image for this purpose.
13 Your ElasticSearch (ES) setup must have the "Delete By Query Plugin" installed.
14 Without this, some of the ES functionality won't work properly.
17 Creating a custom ElasticSearch docker image
18 --------------------------------------------
20 (You can skip this section if you already have an instance of ElasticSearch running)
22 Run the following set of commands:
26 cat << EOF > Dockerfile
28 RUN /usr/share/elasticsearch/bin/plugin install --batch delete-by-query
32 To build the image, run the following command in the directory where the
33 Dockerfile was created:
37 docker build . -t elasticsearch-dd
40 You can check whether the image was properly created by running:
47 This should print all your container images including the elasticsearch-dd.
49 Now we can create and run a container from our image by typing:
53 docker run -d -p 9200:9200 -p 9300:9300 --name elasticsearch-dd elasticsearch-dd
56 To see whether the container is running, run the following command:
63 The output should include a row with elasticsearch-dd in the NAMES column.
64 To check the std out of this container use
68 docker logs elasticsearch-dd
71 Running the ElasticSearch feature
72 ---------------------------------
74 Once the features have been installed, you can change some of its properties. For
75 example, to setup the URL where your ElasticSearch installation runs,
76 change the *serverUrl* parameter in tsdr/persistence-elasticsearch/src/main/resources/configuration/initial/:
78 tsdr-persistence-elasticsearch.properties
81 All the data are stored into the TSDR index under a type. The metric data are
82 stored under the metric type and the log data are store under the log type.
83 You can modify the files in tsdr/persistence-elasticsearch/src/main/resources/configuration/initial/:
85 tsdr-persistence-elasticsearch_metric_mapping.json
86 tsdr-persistence-elasticsearch_log_mapping.json
88 to change or tune the mapping for those types. The changes in those files will be promoted after
89 the feature is reloaded or the distribution is restarted.
95 We can now test whether the setup is correct by downloading and installing mininet,
96 which we use to send some data to the running ElasticSearch instance.
98 Installing the necessary features:
104 feature:install odl-restconf odl-l2switch-switch odl-tsdr-core odl-tsdr-openflow-statistics-collector
105 feature:install odl-tsdr-elasticsearch
107 We can check whether the distribution is now listening on port 6653:
111 netstat -an | grep 6653
117 sudo mn --topo single,3 --controller 'remote,ip=distro_ip,port=6653' --switch ovsk,protocols=OpenFlow13
120 where the distro_ip is the IP address of the machine where the OpenDaylight distribution
121 is running. This command will create three hosts connected to one OpenFlow capable
124 We can check if data was stored by ElasticSearch in TSDR by running the
129 tsdr:list FLOWTABLESTATS
131 The output should look similar to the following::
133 [NID=openflow:1][DC=FLOWTABLESTATS][MN=ActiveFlows][RK=Node:openflow:1,Table:50][TS=1473427383598][3]
134 [NID=openflow:1][DC=FLOWTABLESTATS][MN=PacketMatch][RK=Node:openflow:1,Table:50][TS=1473427383598][12]
135 [NID=openflow:1][DC=FLOWTABLESTATS][MN=PacketLookup][RK=Node:openflow:1,Table:50][TS=1473427383598][12]
136 [NID=openflow:1][DC=FLOWTABLESTATS][MN=ActiveFlows][RK=Node:openflow:1,Table:80][TS=1473427383598][3]
137 [NID=openflow:1][DC=FLOWTABLESTATS][MN=PacketMatch][RK=Node:openflow:1,Table:80][TS=1473427383598][17]
138 [NID=openflow:1][DC=FLOWTABLESTATS][MN=PacketMatch][RK=Node:openflow:1,Table:246][TS=1473427383598][19]
141 Or you can query your ElasticSearch instance:
145 curl -XPOST "http://elasticseach_ip:9200/_search?pretty" -d'{ "from": 0, "size": 10000, "query": { "match_all": {} } }'
147 The elasticseach_ip is the IP address of the server where the ElasticSearch is running.
150 Web Activity Collector
151 ======================
153 The Web Activity Collector records the meaningful REST requests made through the
154 OpenDaylight RESTCONF interface.
157 How to test the RESTCONF Collector
158 ----------------------------------
160 - Install some other feature that has a RESTCONF interface, for example. "odl-tsdr-syslog-collector"
161 - Issue a RESTCONF command that uses either POST,PUT or DELETE.
162 For example, you could call the register-filter RPC of tsdr-syslog-collector.
163 - Look up data in TSDR database from Karaf.
170 - You should see the request that you have sent, along with its information
171 (URL, HTTP method, requesting IP address and request body)
172 - Try to send a GET request, then check again, your request should not be
173 registered, because the collector does not register GET requests by default.
174 - Open the file: "etc/tsdr.restconf.collector.cfg", and add GET to the list of
175 METHODS_TO_LOG, so that it becomes:
178 METHODS_TO_LOG=POST,PUT,DELETE,GET
180 - Try again to issue your GET request, and check if it was recorded this time,
181 it should be recorder.
182 - Try manipulating the other properties (PATHS_TO_LOG (which URLs do we want
183 to log from), REMOTE_ADDRESSES_TO_LOG (which requesting IP addresses do we
184 want to log from) and CONTENT_TO_LOG (what should be in the request's body
185 in order to log it)), and see if the requests are getting logged.
186 - Try providing invalid properties (unknown methods for the METHODS_TO_LOG
187 parameter, or the same method repeated multiple times, and invalid regular
188 expressions for the other parameters), then check karaf's log using
189 "log:display". It should tell you that the value is invalid, and that it
190 will use the default value instead.
