Two kinds of graph can be generated by Cacti:
* using a simple data: data are returned by the probe and are directly and completely graphed,
* or using a data query: data are returned by the probe and must be filtered before to be graphed

{note}The following steps by steps process must be adapted to your metric{note}

h1. Using a simple data

This is done using a simple *script/command* based on Petals CLI to collect metric values.

To create this graph, please follow the following steps:
# First, create a new *Data Input Method*:
!petals-container-localtransporter-dim.jpg|align=center!
Cacti monitoring extension of Petals CLI is used to get metric values. See the documentation of [Petals CLI|petalscomponents:Petals CLI] for more information.
In the *Input String*, you will put the command line arguments to connect to the the Petals node for which you want to graph the delivered messages of the local transporter. That's why the command line contains: *<petals_host>*, *<petals_jmx_port>*, *<petals_jmx_user>* and *<petals_jmx_password>*.
# Add an *input field* for your Petals node hostname
!petals-container-localtransporter-dim-petals-host.jpg|align=center!
As the Petals node hostname can be automatically set from the hostname of the monitored host, the field *Special Type Code* is set.
# Add others *input fields*
!petals-container-localtransporter-dim-petals-jmx-port.jpg|align=center!
As for the JMX port, create an input field for the Petals JMX username and the Petals JMX user password.
# Add the *output fields* returned by the script
For each output fields of the script/command (here, in the sample, for each message exchange status "Active", "Done" and "Error"), create an output field:
!petals-container-localtransporter-dim-output-active.jpg|align=center!
# Check that you have the following *Data Input Method*:
!petals-container-localtransporter-dim-full.jpg|align=center!
# Create a new *Data Template*:
!petals-container-localtransporter-dt.jpg|align=center!

!petals-container-localtransporter-dt-custom.jpg|align=center!

!petals-container-localtransporter-ng.jpg|align=center!
# Set parameters needed to the *Data Input Method*
!petals-container-localtransporter-ng-params.jpg|align=center!

The new graph can be viewed after several minutes needed to collect data. By default a collect is done every 5 minutes. To view the graph, go into *Graph management"

{anchor:Creating a graph using a data query}
h1. Monitoring the delivered messages of the the local transporter to a dedicated endpoint

!petals-delivered-messages-by-endpoint.png|align=center!

This is done using a *data query* to collect metric values. The data query definition to put in the XML file is:
{code}
<interface>
<name>Get Delivered Messages by the Local transporter to an endpoint</name>
<script_path>/home/cdeneux/petals-cli-2.1.1-SNAPSHOT/bin/petals-cli.sh</script_path>
<arg_prepend>-h localhost -n 7700 -u petals -p petals -c -- monitoring -o local-transporter -f delivered-messages</arg_prepend>
<arg_index>-- --list-endpoints</arg_index>
<arg_query>-- --query-endpoints</arg_query>
<arg_get>-- --query-endpoints</arg_get>

<index_order_type>alphanumeric</index_order_type>
<!--index_title_format>|chosen_order_field|</index_title_format-->

<fields>

<activeDeliveredMsgs>
<name>Active Message exchange delivered counter</name>
<direction>output</direction>
<query_name>ACTIVE</query_name>
</activeDeliveredMsgs>
<doneDeliveredMsgs>
<name>Done Message exchange delivered counter</name>

<errorDeliveredMsgs>
<name>Error Message exchange delivered counter</name>
<direction>output</direction>
<query_name>ERROR</query_name>
</errorDeliveredMsgs>
</fields>
</interface>
{code}
Don't forget to adapt the path of Petals CLI to your installation. Petals CLI is used to collect data. See the documentation of [Petals CLI|petalscomponents:Petals CLI] for more information.

To create this graph, please follow the following steps:
# First, create a new *Data Query*:
!petals-container-localtransporter-itf-dq.jpg|align=center!
# Go to the *device* for which you want collect metric values, and associate it to the data query previously created
!petals-container-localtransporter-itf-device-associate.jpg|align=center!
# Create a new *Data Template*:
!petals-container-localtransporter-itf-dt.jpg|align=center!
Select "*Get Script Data (Indexed)*" as *Data Input Method*.
Add your first *data item* associated to the number of delivered messages for message exchange status 'Active'. The *data source type* of the item is *COUNTER*.
# Create two others *data items* associated to the number of delivered messages for message exchange status 'Done' and 'Error'
!petals-container-localtransporter-itf-dt-items.jpg|align=center!
# A new block *Custom data* appears, check *Use Per-Data Source Value* for all
!petals-container-localtransporter-itf-dt-custom.jpg|align=center!
# Create a new *Graph Template*:
!petals-container-localtransporter-itf-gt.jpg|align=center!
# Add a *Graph Item* to displayed graph the number of delivered messages for message exchange status 'Active'
!petals-container-localtransporter-itf-gt-active.jpg|align=center!
# Add a *Graph Item* to displayed the legend of the number of delivered messages for message exchange status 'Active'
!petals-container-localtransporter-itf-gt-active-legend.jpg|align=center!
# Add others *Graph Items* associated to the number of delivered messages for message exchange status 'Done' and 'Error'
!petals-container-localtransporter-itf-gt-full.jpg|align=center!
# Go to the *data query* previoulsy created, and associate it the just create graph template
!petals-container-localtransporter-itf-dq-associate.jpg|align=center!
# Associate outputs of the *data query* to the *graph items*
!petals-container-localtransporter-itf-dq-associate-output.jpg|align=center!
*Don't forget to check boxes.*
# Go to the *device* for which you want to create the graph, and *Create Graphs for this Host*
!petals-container-localtransporter-itf-ng.jpg|align=center!
Select yours endpoints for which you want create a graph

The new graph can be viewed after several minutes needed to collect data. By default a collect is done every 5 minutes. To view the graph, go into *Graph management"
