SIREMIS is able to create and display charts using echarts javascript library (BSD3-clause license) – the library is included in SIREMIS distribution, you do not need to do anything else.
The data to create the charts is taken from tables residing in Kamailio database. There are no such tables by default – the installation wizard of Siremis creates a table statistics with some predefined metrics, you can extend it if you need or create another one following the same kind of structure.
The table has to include a column that stores the time stamp. These values are used for X-axis. The other columns have to store integer values representing time-dependency of a particular attribute.
Besides the dynamic charts, the Charts Pannel includes views for charts or summaries generated from other Kamailio tables, such as location or acc. For these ones, there is no need to do anything, just load the appropriate modules in Kamailio and configure them with database storage support.
There are two ways to get data from Kamailio and populate tables to be used for charts:
An example of SIP Proxy configuration snippets for the statistics printed by default Siremis charts:
loadmodule "rtimer.so" loadmodule "sqlops.so" loadmodule "htable.so" ... modparam("rtimer", "timer", "name=tst;interval=300;mode=1;") modparam("rtimer", "exec", "timer=tst;route=STATS") modparam("sqlops","sqlcon", "ca=>mysql://kamailio:kamailiorw@localhost/kamailio") modparam("htable", "htable", "stats=>size=6;") ... route[STATS] { # clean very old records $var(tmc) = $var(tmc) + 1; $var(x) = $var(tmc) mod 144; if($var(x) == 0) sql_query("ca", "delete from statistics where time_stamp<$Ts - 864000", "ra"); # insert values for Kamailio internal statistics sql_query("ca", "insert into statistics (time_stamp,shm_used_size," "shm_real_used_size,shm_max_used_size,shm_free_used_size," "ul_users,ul_contacts) values ($Ts,$stat(used_size)," "$stat(real_used_size),$stat(max_used_size),$stat(free_size)," "$stat(location-users),$stat(location-contacts))", "ra"); # init the values for first execution, compute the diff for the rest if($var(tmc)==1) { $var(rcv_req_diff) = $stat(rcv_requests); $var(fwd_req_diff) = $stat(fwd_requests); $var(2xx_trans_diff) = $stat(2xx_transactions); } else { $var(rcv_req_diff) = $stat(rcv_requests) - $sht(stats=>last_rcv_req); $var(fwd_req_diff) = $stat(fwd_requests) - $sht(stats=>last_fwd_req); $var(2xx_trans_diff) = $stat(2xx_transactions) - $sht(stats=>last_2xx_trans); } # update the values for stats stored in cache (htable) $sht(stats=>last_rcv_req) = $stat(rcv_requests); $sht(stats=>last_fwd_req) = $stat(fwd_requests); $sht(stats=>last_2xx_trans) = $stat(2xx_transactions); # insert values for stats computed in config sql_query("ca", "update statistics set tm_active=$stat(inuse_transactions)," "rcv_req_diff=$var(rcv_req_diff),fwd_req_diff=$var(fwd_req_diff)," "2xx_trans_diff=$var(2xx_trans_diff) where time_stamp=$Ts", "ra"); }
Kamailio statistics table was created by Siremis Web Installation Wizard by checking “Update SIP Database” option in Step 2. You will see a new table named 'statistics'.
Now all is ready for Kamailio, you can restart it.
The configuration file for charts panel is located at:
siremis/modules/sipadmin/service/siremisCharts.xml
The content of the file looks like:
<?xml version="1.0" standalone="no"?> <PluginService Name="siremisCharts" Package="asipto" Class="siremisCharts"> <ChartGroup name="tm"> <Chart name="tm" table="statistics" title="TM Stats" bgcolor="#FFF8C6" order="reverse" orderby="ORDER BY id DESC" limit="LIMIT 120"> <XAxis> <Item name="time_stamp" data="time_stamp" title="timestamp" type="timestamp"/> </XAxis> <YAxis> <Item name="tm_active" data="tm_active" title="Active Transactions" type="dataset"/> </YAxis> </Chart> <Chart name="tm200okload" table="statistics" title="TM 2xx Trans Load" bgcolor="#C3FDB8" order="reverse" orderby="ORDER BY id DESC" limit="LIMIT 120"> <XAxis> <Item name="time_stamp" data="time_stamp" title="timestamp" type="timestamp"/> </XAxis> <YAxis> <Item name="2xx_trans_diff" data="2xx_trans_diff" title="2xx trans" type="dataset" color="#FBB917" /> </YAxis> </Chart> </ChartGroup> <ChartGroup name="shm"> <Chart name="shm" table="statistics" title="Shared Memory" bgcolor="#40E046" type="area" order="reverse" orderby="ORDER BY id DESC" limit="LIMIT 120"> <XAxis> <Item name="time_stamp" data="time_stamp" title="timestamp" type="timestamp"/> </XAxis> <YAxis> <Item name="shm_used_size" data="shm_used_size" title="Used Size" type="dataset" color="#DFC329"/> <Item name="shm_real_used_size" data="shm_real_used_size" title="Real Used Size" type="dataset" color="#5E4785"/> </YAxis> </Chart> <Chart name="shmused" table="statistics" title="Used Shared Memory" bgcolor="#B0E0E6" type="area" order="reverse" orderby="ORDER BY id DESC" limit="LIMIT 120"> <XAxis> <Item name="time_stamp" data="time_stamp" title="timestamp" type="timestamp"/> </XAxis> <YAxis> <Item name="shm_max_used_size" data="shm_max_used_size" title="Max Used Size" type="dataset" color="#6363AC"/> </YAxis> </Chart> </ChartGroup> <ChartGroup name="usrloc"> <Chart name="usrloc" table="statistics" title="Location" type="area" order="reverse" orderby="ORDER BY id DESC" limit="LIMIT 120"> <XAxis> <Item name="time_stamp" data="time_stamp" title="timestamp" type="timestamp"/> </XAxis> <YAxis> <Item name="ul_users" data="ul_users" title="users" type="dataset" color="#D02020"/> <Item name="ul_contacts" data="ul_contacts" title="contacts" type="dataset" color="#DFC329"/> </YAxis> </Chart> </ChartGroup> <ChartGroup name="load"> <Chart name="rreqload" table="statistics" title="Rcv Reqs" type="area" bgcolor="#FFFFCC" order="reverse" orderby="ORDER BY id DESC" limit="LIMIT 120"> <XAxis> <Item name="time_stamp" data="time_stamp" title="timestamp" type="timestamp"/> </XAxis> <YAxis> <Item name="rcv_req_diff" data="rcv_req_diff" title="Rcv Reqs Load" type="dataset" color="#990000" /> </YAxis> </Chart> <Chart name="freqload" table="statistics" title="Rcv Reqs" bgcolor="#66CC99" order="reverse" orderby="ORDER BY id DESC" limit="LIMIT 120"> <XAxis> <Item name="time_stamp" data="time_stamp" title="timestamp" type="timestamp"/> </XAxis> <YAxis> <Item name="fwd_req_diff" data="fwd_req_diff" title="Fwd Reqs Load" type="dataset" color="#330099" /> </YAxis> </Chart> </ChartGroup> </PluginService>
There are couple of relevant XML nodes in the configuration file
The attributes for each XML node are pretty self-suggestive. The ‘name’ has to be unique and ‘data’ in the ‘Item’ node represents the column name in the table from where to fetch the values.
To add new chart page in SIREMIS you have add a new file in directory:
siremis/modules/sipadmin/view/
Say it is named ChartsCgnameView.xml, its content has to be:
<?xml version="1.0" standalone="no"?> <EasyView Name="ChartsCgnameView" Description="Charts" class="EasyView" Tab="" TemplateEngine="Smarty" TemplateFile="view.tpl"> <FormReferences> <Reference Name="sipadmin.cms.form.ChartsForm"/> </FormReferences> </EasyView>
Then, to add it to menu, update the file:
siremis/modules/sipadmin/mod.xml
Find the XML node:
<MenuItem Name="System.Sipadmin.Charts" Title="Chart Services" Parent="System.Sipadmin" ...>
and add a new subnode.
The URL for View node has to be “/siremis/sipadmin/charts_cgname/cg=cgname”, where cgname is the value of name attribute for a ChartGroup.
Then, in Siremis web interface, go to Administration panel and reload module sipadmin (under tab Modules).
