RuntimeError: ('label contains illegal characters', "Getting Queue(s) FAILED: 'value'")

[lremes]

I'm evaluting the plugin on Centos7 and with ActiveMQ 5.12.0. AMQ is running at localhost:8161.

I get the following error running the examples:

# ./check_activemq.py queuesize
ACTIVEMQQUEUESIZE UNKNOWN: RuntimeError: ('label contains illegal characters', "Getting Queue(s) FAILED: 'value'")
Traceback (most recent call last):

    raise RuntimeError('label contains illegal characters', label)
RuntimeError: ('label contains illegal characters', "Getting Queue(s) FAILED: 'value'")

Even the most basic check does not work:

# ./check_activemq.py health
ACTIVEMQHEALTH UNKNOWN - ERROR: Getting Values FAILED: 'value'
unknown: ERROR: Getting Values FAILED: 'value'

I've tried with both nagiosplugin 1.2.2 and 1.2.3 and Python is 2.7.5

Any tips how to fix this?

First time I see this error, it seems to be thrown HERE. The underlying problem it that this call

loadJson(make_url(args, queue['objectName']))

in line 79 of the activemq-nagios-pugin returns a dictionary which doesn't have a key named 'value'.

As this problem never occured in my tests, could you subsitute line 79 with

qJ1 = loadJson(make_url(args, queue['objectName']))
print(qJ1)
qJ = qJ1['value']

and paste me the results.

It seems the error has something to do with invalid AMQ url. When I changed the PREFIX to "localhost:", things started working. So this works:

http://admin:admin@localhost:8161/api/jolokia/read/localhost:type=Broker,brokerName=localhost,service=Health

any chances of a fix being pushed out for this?

Hello: I am also having this very issue and I'm here to provide more details, hoping it can lead to a solution.

I've used this plugin for a year with no issues (thanks). I monitor a few master-slave, two-node, ActiveMQ clusters with shared NFS kahaDB file system. Last week, we implemented a change on our ActiveMQ configuration and started having this issue. Basically, we enabled scheduler on our ActiveMQ cluster by making this change on activemq.xml configuration file for each member of the cluster ...

From this -> <broker xmlns="http://activemq.apache.org/schema/core" brokerName="localhost" dataDirectory="${activemq.data}/localhost">

To this -> <broker xmlns="http://activemq.apache.org/schema/core" brokerName="<hostname>" dataDirectory="${activemq.data}/<hostname>" schedulerSupport="true">

Clusters were restarted and verified with scheduling support for queues, but Nagios monitoring via 'check_activemq.py' stopped working...

I'm getting this now ->

/root/check_activemq.py --host <cluster_node1> --port 8161 --user admin --pwd <password> health ACTIVEMQHEALTH UNKNOWN - ERROR: Getting Values FAILED: 'value' unknown: ERROR: Getting Values FAILED: 'value'

[r41d]

Never had this issue, could you replace this

status = loadJson(health_url(args))['value']['CurrentStatus']

in the health test with

print("args:", args)
s1 = loadJson(health_url(args))
print("s1:", s1)
status = s1['value']['CurrentStatus']
print("status:", status)

and paste the output somewhere.

Thanks for taking a look, here is the output

By changing the brokername the JMX URI also changes. Then a query for:

org.apache.activemq:type=Broker,brokerName=localhost,service=Health

fails. Have you tried to set the brokername using:

--brokerName <<Brokername>>

?

[mengano-net]

Yup, that was it. I'd be awesome if you could put this as a parameter to script; if not specified, then default to 'localhost'. For now, I've added it as a variable that can be specified on demand 👍
