_This is for 8.1 but curious about 8.3 too._ I would like to raise an alarm and warning inside 2 tags whenever the gateway logs have an error or warning occur, with some logic around clearing this out when no error/warnings over x time. I'm wondering the best way to check the latest logs? I'm sure I remember a post showing how to get this through the gateway context, but haven't found it yet. ---

This may be what you were looking for: > [@Accessing Diagnostic Logs in Perspective](https://forum.inductiveautomation.com/t/accessing-diagnostic-logs-in-perspective/66954): > > I would like to display the diagnostic logs from the gateway into a perspective container. Is this possible? I was not able to find a function that does this in the manual nor did I find anything on the exchange. …or at least a place to start. ---

(Found it! Thanks @tyler.bennett [Accessing Diagnostic Logs in Perspective - #6 by tyler.bennett](https://forum.inductiveautomation.com/t/accessing-diagnostic-logs-in-perspective/66954/6)) @lane.duncan I had this prepped a while ago and was going to add to it where I ended up at, but got distracted working 😅 Thanks for your reply with it though. I will update this post shortly with the above ---

I ended up with this, where `updateGatewayLogLevelCountTags()` is called every minute from a GW timer script, and the Alarm Count tag has an alarm on it for value \> 0 ```python try: from com.inductiveautomation.ignition.gateway import IgnitionGateway from com.inductiveautomation.ignition.common.logging import LogQueryConfig except: pass def getGatewayLogLevelCounts(timePeriodMin=5, logRetrievalLimit=2000): '''Retrieves the count of each log level from the gateway logs for the last {timePeriodMin} minutes. Queries the gateway's internal log store (the same data backing the Status > Diagnostics > Logs page) via the unsupported/internal IgnitionGateway logging manager API, then tallies how many events fall into each standard log level. IMPORTANT: must run in the gateway context. Args: timePeriodMin (int): How many minutes back from now to query, e.g. 5 for the last 5 minutes. logRetrievalLimit (int): Max number of log events to pull from the query. Acts as a safety cap on a noisy window - if this limit is being hit regularly, counts will be undercounted and the limit should be raised. Returns: dict: Counts keyed by level name - {'ERROR': int, 'WARN': int, 'INFO': int, 'TRACE': int, 'DEBUG': int}. Raises: ValueError: If the gateway log query fails for any reason (e.g. not running in gateway scope, or the internal logging API is unavailable/changed). ''' try: now = system.date.now() windowStart = system.date.addMinutes(now, -1 * timePeriodMin) startMillis = system.date.toMillis(windowStart) loggingManager = IgnitionGateway.get().getLoggingManager() queryBuilder = LogQueryConfig.newBuilder() queryBuilder.newerThan(startMillis) queryBuilder.limitTo(logRetrievalLimit) # generous cap - raise if you're hitting the limit in a noisy 5min window logResults = loggingManager.queryLogEvents(queryBuilder.build()) logEvents = logResults.getEvents() logLevelCounts = {'ERROR': 0, 'WARN': 0, 'INFO': 0, 'TRACE': 0, 'DEBUG': 0} for event in logEvents: level = str(event.getLevel()).upper() logLevelCounts[level] += 1 return logLevelCounts except Exception, e: raise ValueError("Failed to query gateway logs and update alarm count tags: %s" % str(e)) def updateGatewayLogLevelCountTags(): '''Updates the gateway alarm count tags with ERROR and WARN log counts from the last 5 minutes. Calls getGatewayLogLevelCounts() for a 5-minute window and writes the resulting ERROR and WARN counts to their respective alarm tags. Intended to be called on a recurring basis (e.g. from a 1-minute Gateway Timer Event) so the tags stay current with a rolling 5-minute count, dropping back to 0 once no matching log events remain in the window. IMPORTANT: must run in the gateway context (see getGatewayLogLevelCounts). Tags written: [default]System/Alarms/Gateway Application Error Count [default]System/Alarms/Gateway Application Warn Count ''' logLevelCounts = getGatewayLogLevelCounts(timePeriodMin=5) errorCount = logLevelCounts['ERROR'] warnCount = logLevelCounts['WARN'] errorTagPath = "[default]System/Alarms/Gateway Application Error Count" warnTagPath = "[default]System/Alarms/Gateway Application Warn Count" system.tag.writeBlocking([errorTagPath, warnTagPath], [errorCount, warnCount]) ```
