I have a proxy service in wso2. This service uses the ftp settings with which I download files. But sometimes it doesn't work as I expect it to. How can I check the ftp connection in wso2 and, if I get a timeout or connection refused, make a reconnection?
It is parameters of my proxy service in wso2
<parameter name="transport.vfs.ContentType">text/plain;charset=UTF-8</parameter>
<parameter name="transport.vfs.FileURI">vfs:ftp://login:password#host/outgoing</parameter>
<parameter name="transport.vfs.ActionAfterProcess">DELETE</parameter>
<parameter name="transport.vfs.MoveAfterFailure">vfs:ftp://login:password#host/outgoing/error</parameter>
<parameter name="transport.vfs.ActionAfterFailure">MOVE</parameter>
<parameter name="transport.vfs.FileNamePattern">.*\.csv</parameter>
<parameter name="transport.vfs.Locking">disable</parameter>```
You can set the following parameter.
transport.vfs.MaxRetryCount

HttpMonitor Config was working fine with tomcat7 and http service was getting detected however as we have updated to tomcat 8.5 http service is not getting discovered unless we set connector properties as sendReasonPhrase=true, the difference in the curl response is like below in compare to tomcat7 and tomcat 8.5 (withoutsend Reson Phrase parameter set)
tomcat7 gives ok in its header and tomcat8.5 does not.
however option for sendreson phase will be deprecated and removed from tomcat9 and even this option will not be available (https://tomcat.apache.org/tomcat-8.5-doc/config/http.html)
I am not sure why httpMonitor in openNms is not able to detect the http service even the snmpwalk output see port 80 available (both with and without send reason phrase)
in poller-configuration.xml looks like below for http
<service name="HTTP" interval="300000" user-defined="false" status="on">
<parameter key="retry" value="1"/>
<parameter key="timeout" value="3000"/>
<parameter key="port" value="80"/>
<parameter key="url" value="/"/>
<parameter key="rrd-repository" value="/var/lib/opennms/rrd/response"/>
<parameter key="rrd-base-name" value="http"/>
<parameter key="ds-name" value="http"/>
</service>
even we tried setting
<parameter key="response-text" value="~\bOK\b"/>
and
<parameter key="response" value="200"/>
however it did not help, i guess above parameter play its role once service got discovered however the problem here the service is not getting discovered (unless SendReson pharse is turn on ) it will only detect http service in tomcat 8.5 if we have sendreson phase turn on in connector definition inside server.xml
Kindly help to understand this behaviour here and possible solution for this without any change on client side.
openNms version info:
Defined a proxy-service and need to access service parameters from registry. The below syntax is not working.
<parameter name="transport.vfs.FileURI">"conf:/repository/FileLocation"</parameter>
<parameter name="transport.vfs.MoveAfterFailure">"conf:/repository/FileMoveAfterFailure"</parameter>
<parameter name="transport.vfs.FileNamePattern">"conf:/repository/FilePattern"</parameter>
<parameter name="transport.vfs.MoveAfterProcess">"conf:/repository/FileMoveAfterProcess"</parameter>
How to access registry values under /_system/config/repository to use in proxy service parameters?
As far as I know you cannot, the only option is to create a "file" inbound endpoint
<inboundEndpoint name="test_Inbound" protocol="file" sequence="test_Process" suspend="false" xmlns="http://ws.apache.org/ns/synapse">
<parameters>
<parameter name="interval">5000</parameter>
<parameter name="sequential">true</parameter>
<parameter name="coordination">true</parameter>
<parameter name="transport.vfs.ContentType">text/plain</parameter>
<parameter name="transport.vfs.LockReleaseSameNode">false</parameter>
<parameter name="transport.vfs.AutoLockRelease">false</parameter>
<parameter name="transport.vfs.ActionAfterFailure">MOVE</parameter>
<parameter name="transport.vfs.ActionAfterProcess">MOVE</parameter>
<parameter key="conf:/repository/FileLocation" name="transport.vfs.FileURI"/>
<parameter key="conf:/repository/FileMoveAfterFailure" name="transport.vfs.MoveAfterFailure"/>
<parameter name="transport.vfs.DistributedLock">false</parameter>
<parameter key="conf:/repository/FilePattern" name="transport.vfs.FileNamePattern"/>
<parameter key="conf:/repository/FileMoveAfterProcess" name="transport.vfs.MoveAfterProcess"/>
<parameter name="transport.vfs.Locking">disable</parameter>
<parameter name="transport.vfs.CreateFolder">true</parameter>
<parameter name="transport.vfs.Streaming">false</parameter>
<parameter name="transport.vfs.Build">false</parameter>
</parameters>
</inboundEndpoint>
Then you have to do your processing in a sequence (test_Process), and of course adapt to your parameters (ContentType, interval, sequential or not....)
I never tried for transport.vfs.FileNamePattern but for the other I'm sure it's working as I'm using it.
I have a MIB with oids and events. The device the MIB relates to is online. OpenNMS sees and gathers information about the interfaces on the appliance, as well as the linux variant it is running.
but it doesn't see the other oids (or I can't find/chart them).
The gui reports Polling Status (Managed) and Package (uti_p). The uti_p package is
<package name="uti_p">

I have a collectd-configuration

The .../rrd/snmp/{node} directory does not show any collection of data for the various oids that I am looking for.
In response to comments:
$ snmpwalk -v 2c -c FIPS14023 10.19.0.204 iso.3.6.1.4.1.nnnn
...
iso.3.6.1.4.1.nnnn.1.1.10.0 = INTEGER: 29
iso.3.6.1.4.1.nnnn.1.1.11.0 = STRING: "29.0"
...
i.e., it returns the expected data from the MIB.
The Community set in OpenNMS is FIPS14023, and the automatic discovery process finds the node.
Node Hsm.204
Interface 10.19.0.204
Polling Status Managed
Polling Package uti_p
Monitor Class org.opennms.netmgt.poller.monitors.SnmpMonitor
Service Parameters
oid .1.3.6.1.4.1.nnnn
The Requisition name for the class of appliance is correct.
I just can find where the above String "29.0" is supposed to appear. As I understand it, the data should be collected into RRD db files, but the node Database IDs never show up in the /etc/opennms/rrdsnmp directory.

Thank you!
I would debug the SNMP access as the following with assuming you have SNMP v2 setup:
Test access to SNMP agent from your OpenNMS server with snmpwalk -v 2c -c
OpenNMS associates SNMP community strings with the IP address. You can verify this in the Web UI in "Admin -> Configure OpenNMS -> Configure OpenNMS Community Names by IP Address" and use the "Lookup" field. It will show you which SNMP community is configured for your device and fix this if necessary.
Go to the node page and rescan the server and see if the "SNMP Attributes" fields with IP and physical interfaces get filled.
If Step 1 does not give you the full SNMP tree you have to fix your surrounding configuration, IP tables or SNMP agent configuration for views and community.
Is there a reason you are defining a different collection set "HsmLan" over the default collection for SNMP in collectd?
Be sure to include the collection service at the bottom of collectd-configuration.xml for HsmLan, ala:
<collector service="HsmLan" class-name="org.opennms.netmgt.collectd.SnmpCollector"/>
If there is, you need to define this "snmp-collection" in datacollection-config.xml and include collections via the tag which references collections named in xml files (that have OIDs, etc) in etc/datacollection/
The poller-configuration.xml you listed at the top has no bearing on data collection. It is for service polling.
I'm using wso2esb4.7.0 and wso2mb-2.2.0. I wish to create jms proxy service using wso2mb. For this i have configured the wso2mb as well as wso2esb like :
Wso2esb configuration :
(changes in jndi.properties)
# register some connection factories
# connectionfactory.[jndiname] = [ConnectionURL]
connectionfactory.QueueConnectionFactory = amqp://admin:admin#clientID/carbon?brokerlist='tcp://localhost:5673'
connectionfactory.TopicConnectionFactory = amqp://admin:admin#clientID/carbon?brokerlist='tcp://localhost:5673'
# register some queues in JNDI using the form
# queue.[jndiName] = [physicalName]
queue.MyQueue = MyQueue
changes in axis2.xml :
uncomment following code :

also copied andes-client-*.jar and geronimo-jms_1.1_spec-*.jar from $MB_HOME/client-lib to $ESB_HOME/repository/components/lib
re-started servers.Till it's working fine.
Now wish to create a service with jms port. it is creating a service but immediately it goes to faulty service and esb logs it showing error like :

also while restarting it showing error like :

My proxy configuration is :

<outSequence>
<drop/>
</outSequence>
Why so? is their any problem with jms configuration? Please guide me.
in jndi.properties, you've defined :
QueueConnectionFactory
TopicConnectionFactory
and in axis.xml, you use :
QueueConnectionFactory
TopicConnectionFactory
AND, in the default part, a "ConnectionFactory"
I don't use WSO2MB by I wonder if this would not be your problem
I was wondering how to configure a JMS transport to work with IBM MessageSight, similar to: http://docs.wso2.org/display/ESB460/Configure+with+ActiveMQ
Right now, I have the following in axis2.xml:
<transportReceiver name="ibmMsgSightJMS" class="org.apache.axis2.transport.jms.JMSListener">
<parameter name="myTopicConnectionFactory" locked="false">
<parameter name="java.naming.factory.initial" locked="false">com.ibm.ima.jms.ImaJmsFactory</parameter>
<parameter name="java.naming.provider.url" locked="false">tcp://192.168.154.128:1883</parameter>
<parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">TopicConnectionFactory</parameter>
<parameter name="transport.jms.ConnectionFactoryType" locked="false">topic</parameter>
</parameter>
<parameter name="myQueueConnectionFactory" locked="false">
<parameter name="java.naming.factory.initial" locked="false">com.ibm.ima.jms.ImaJmsFactory</parameter>
<parameter name="java.naming.provider.url" locked="false">tcp://192.168.154.128:1883</parameter>
<parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">QueueConnectionFactory</parameter>
<parameter name="transport.jms.ConnectionFactoryType" locked="false">queue</parameter>
</parameter>
<parameter name="default" locked="false">

<parameter name="java.naming.provider.url" locked="false">tcp://192.168.154.128:1883</parameter>
<parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">QueueConnectionFactory</parameter>
<parameter name="transport.jms.ConnectionFactoryType" locked="false">queue</parameter>
</parameter>
</transportReceiver>
And I have something like this in an ESB proxy service:
<proxy xmlns="http://ws.apache.org/ns/synapse"
name="esbProcessMqttJMSPS" statistics="disable" trace="disable" transports="ibmMsgSightJMS">
<parameter name="transport.jms.ConcurrentConsumers">1</parameter>
<parameter name="transport.jms.ConnectionFactory">myTopicConnectionFactory</parameter>
<parameter name="transport.jms.DestinationType">B</parameter>
<parameter name="transport.jms.Destination">B</parameter>
</proxy>
When I startup the ESB server, I get the following error: Cannot acquire JNDI context, JMS Connection factory : TopicConnectionFactory or default destination : null for JMS CF
Any help would be greatly appreciated. Thanks!
Okay so I figured this out.
The jms config in axis2.xml should be:
<transportReceiver name="ibmMsgSightJMS" class="org.apache.axis2.transport.jms.JMSListener">
<parameter name="myTopicConnectionFactory">
<parameter name="java.naming.factory.initial" locked="false">com.sun.jndi.fscontext.RefFSContextFactory</parameter>
<parameter name="java.naming.provider.url" locked="false">file:/C:/path/to/wso2/repository/conf/jndi</parameter>
<parameter name="transport.jms.ConnectionFactoryJNDIName" locked="false">connFactory1</parameter>
<parameter name="transport.jms.ConnectionFactoryType" locked="false">topic</parameter>
</parameter>
<parameter name="myQueueConnectionFactory">
<parameter name="java.naming.factory.initial">com.sun.jndi.fscontext.RefFSContextFactory</parameter>
<parameter name="java.naming.provider.url">file:/C:/path/to/wso2/repository/conf/jndi</parameter>
<parameter name="transport.jms.ConnectionFactoryJNDIName">connFactory1</parameter>
<parameter name="transport.jms.ConnectionFactoryType">queue</parameter>
</parameter>
<parameter name="default">
<parameter name="java.naming.factory.initial">com.sun.jndi.fscontext.RefFSContextFactory</parameter>
<parameter name="java.naming.provider.url">file:/C:/path/to/wso2/repository/conf/jndi</parameter>
<parameter name="transport.jms.ConnectionFactoryJNDIName">connFactory1</parameter>
<parameter name="transport.jms.ConnectionFactoryType">topic</parameter>
</parameter>
</transportReceiver>
And I have a jndi properties file named .bindings with the following:
connFactory1/ClassName=com.ibm.ima.jms.impl.ImaConnectionFactory
connFactory1/FactoryName=com.ibm.ima.jms.impl.ImaConnectionFactory
connFactory1/RefAddr/0/Encoding=String
connFactory1/RefAddr/0/Type=Port
connFactory1/RefAddr/0/Content=16102
connFactory1/RefAddr/1/Encoding=String
connFactory1/RefAddr/1/Type=Server
connFactory1/RefAddr/1/Content=192.168.154.128
connFactory1/RefAddr/2/Encoding=String
connFactory1/RefAddr/2/Content=common
connFactory1/RefAddr/2/Type=ObjectType
RequestTopic/ClassName=com.ibm.ima.jms.impl.ImaTopic
RequestTopic/FactoryName=com.ibm.ima.jms.impl.ImaTopic
RequestTopic/RefAddr/0/Encoding=String
RequestTopic/RefAddr/0/Type=Name
RequestTopic/RefAddr/0/Content=testRequestTopic
ResponseTopic/ClassName=com.ibm.ima.jms.impl.ImaTopic
ResponseTopic/FactoryName=com.ibm.ima.jms.impl.ImaTopic
ResponseTopic/RefAddr/0/Encoding=String
ResponseTopic/RefAddr/0/Type=Name
ResponseTopic/RefAddr/0/Content=testResponseTopic
Also, don't forget to put the ImaJmsClient.jar inside components/lib.
I am still having issues where every service is creating topics/queues, and because they are not defined in .bindings, the server is puking. I have worked around this by removing the jms transport protocol on every data service and jar service.
