Hi, I am currently working to build alerting based on the threads or heap memory. Can some one help me to get the performance values likes total threads, waiting threads, heap memory etc using scripting in project... Thanks in advance .... ---

If you get a GatewayContext (search here on the forums), you can also pull out some Ignition specific metrics from the MetricRegistry: [https://files.inductiveautomation.com/sdk/javadoc/ignition81/8.1.22/com/inductiveautomation/ignition/gateway/model/GatewayContext.html](https://files.inductiveautomation.com/sdk/javadoc/ignition81/8.1.22/com/inductiveautomation/ignition/gateway/model/GatewayContext.html) ---

This is what I use ```auto def getGatewayMetrics(): fn = 'getGatewayMetrics' from com.inductiveautomation.ignition.gateway import IgnitionGateway try: context = IgnitionGateway.get() registry = context.getMetricRegistry() metrics = {} items = registry.getCounters() for item in items: #LOGGER.info('{}: {}'.format(fn, ', '.join(d for d in dir(item)))) o = items.get(item) metrics[item] = {'type': 'counter', 'value': o.getCount() } items = registry.getMeters() for item in items: o = items.get(item) metrics[item] = {'type': 'meter', 'value_1min': o.getOneMinuteRate(), 'value_5min': o.getFiveMinuteRate(), 'value_15min': o.getFifteenMinuteRate() } items = registry.getGauges() for item in items: o = items.get(item) metrics[item] = {'type': 'gauge', 'value': o.getValue() } # for item in registry.getHistograms(): items = registry.getTimers() for item in items: o = items.get(item) metrics[item] = {'type': 'timer', 'value_1min': o.getOneMinuteRate(), 'value_5min': o.getFiveMinuteRate(), 'value_15min': o.getFifteenMinuteRate() } except: import traceback LOGGER.error('{}: {}'.format(fn, traceback.format_exc())) return {} return metrics ``` To write the thread count metrics to tags, I use: ```auto def writeMetricsTags(): fn = 'writeMetricsTags' try: metrics = getGatewayMetrics() if metrics != {}: tags = [] # updated the metrics keys after upgrading from 8.1.5 to 8.1.18 as these changed tags.append(['[default]Gateway/{}/Threads/Blocked'.format(THIS_GATEWAY_HOSTNAME), metrics['ignition.performance.threads.blocked']['value']]) tags.append(['[default]Gateway/{}/Threads/Running'.format(THIS_GATEWAY_HOSTNAME), metrics['ignition.performance.threads.running']['value']]) tags.append(['[default]Gateway/{}/Threads/Timed_Waiting'.format(THIS_GATEWAY_HOSTNAME), metrics['ignition.performance.threads.timed-waiting']['value']]) tags.append(['[default]Gateway/{}/Threads/Waiting'.format(THIS_GATEWAY_HOSTNAME), metrics['ignition.performance.threads.waiting']['value']]) system.tag.writeBlocking([tag for tag,val in tags], [val for tag,val in tags]) except: import traceback LOGGER.error('{}: {}'.format(fn, traceback.format_exc())) ``` ---

Hey, Thanks for your reply, am getting error "cannot import name IgnitionGateway". Kindly pls share the process to get things done... Thanks in advance ---

That import is deliberately undocumented because you can do dangerous things with it. If you cannot figure out how to use that import,and _where_ you can use it, it might be too dangerous for you. But examples are scattered around this forum, if you really must. Paul (an IA employee) very deliberately did not give you an example. Whatever you do, don't bother IA support with any trouble you run into as a consequence. The link I posted is for bog-standard and safe java functionality. ---

As a hint, you can only run this from the gateway scope. And if you don't edit my script too much, you won't get yourself into trouble
