Alert Can't connect https, but can curl from collector
Got an issue where getting a status "5", can't connect on https-443 to a web server on AWS EC2. But can connect to https site from public browser and using curl from the collector, without issue. Running diagnostics through LM shows a timeout. The "Poll Now" data looks fine except Normal Datapoints shows errors. These errors cannot be confirmed.210Views0likes6Comments
Cloud Collector to Consume AWS RDS Enhanced Monitoring
It looks like someone in my org had enabled "Enhanced Monitoring" for several AWS RDS instances--a surprise, to be sure, but a welcome one . I would love Cloud Collector method that can consume this data and display it along side all other metrics we are collecting in LogicMonitor. Implementation should be relatively simple. In the discovery, presumably using describe-db-instances, we would just need a system.aws* property for the "dbiresourceid" which can be used to get-log-events.30Views0likes1Comment
Updated AWS EC2 ScheduledEvents
HCPFGA The default LogicMonitor datasource names the instances in a strange way and then alerts for events that have already completed. I've added a better instance naming convention that clearly identifies the event that will occur and when. I also put in logic to detect if the scheduled event has already taken place to prevent unnecessary alerting.28Views2likes5CommentsAnyone else seeing clear-text credentials on their EBS volumes?
We're seeing top-level credentials in clear-text under our EBS volumes. I have not noticed this before so I suspect this is due to a recent saas controller update. For example: the snmp.community appears hashed out at the top of the page, and appears again at the bottom as "system.mmunity" and the value is in clear text. Other, very sensitive credentials are also displayed. I'm currently number 4 in the queue waiting to speak with a rep about this, but I wanted to see if anyone else is experiencing this. For obvious reasons, I won't be screenshotting this. I would urge everyone to check their accounts to see if they are seeing something similar.25Views0likes2CommentsDimensionless Cloudwatch Metrics
I've been creating datasources to collect our custom AWS Cloudwatch metrics as per the docs: https://www.logicmonitor.com/support/monitoring/cloud/monitoring-custom-cloudwatch-metrics/ - mainly this is fine... However it can't cope with dimensionless metrics: " Namespace>Dimensions>Metric>AggregationMethod , where Dimensions should be one or more key value pairs" I've tried creating datapoints without a dimension but it returns NAN (probably because LM requires "one or more key value pairs" for dimensions). We currently use a Python script to collect most our custom metrics but it's resource intensive for our collectors and I'm trying to move away from it. Does anyone know of a way to use the 'AWS CLOUDWATCH' collector with dimensionless metrics?24Views0likes5CommentsCustom CloudWatch Metrics without a host
We have some custom CloudWatch metrics we'd like to gather, display and alert on however, they aren't specific to any host or AWS resource. If we push application specific metrics into CloudWatch, we don't want them tied to any specific application host as hosts/instances can come-and-go. We push these metrics to CloudWatch without an associated EC2 / AWS resource and can see them in CloudWatch, but without an InstanceID, we can not pull these metrics into Logic Monitor. We'd like to be able to pull in and organize any metric from CloudWatch, regardless of whether or not its dimensions include an InstanceID etc.24Views1like3CommentsAWS_ClassicELB_ServiceLimits -- ListenerLimit & ListenerUsage
AWS lists that the Listener limit is on a per ELB basis. The AWS_ClassicELB_ServiceLimits datasource seems to intimate that the ListenerUsage is returning the total number of listeners for the given region. Is this useful information to capture on a regional basis or should this be refactored to apply to each classic ELB?Solved20Views0likes1CommentDatasource for API Gateway Resources behind a stage
I have been using a custom datasource to collect the metrics for each resource and method (excluding OPTIONS) behind a API Gateway stage. It has been extremely useful in our production environments. I would share the datasource via the Exchange, but the discovery method I'm using will not be universal, so I think it would be best if that discovery were to work natively. If possible, could we please have a discovery method for AWS API Gateway Resources by Stage? *Something to note - This has the potential to discover quite a few resources and thus, create a substantial number of cloudwatch calls which might hit customer billing. For this reason, I added a custom property ##APIGW.stages## so that I could plug in the specific stages I wish to monitor instead of having each one automatically discovered. The Applies To looks like this: system.cloud.category == "AWS/APIGateway" && apigw.stages Autodiscovery is currently written in PowerShell (hence why not everyone can take advantage of it) $apigwID = '##system.aws.resourceid##'; $region = '##system.aws.region##' $stages = '##APIGW.Stages##'; $resources = Get-AGResourceList -RestApiId $apigwID -region $region $stages.split(' ') | %{ $stage = $_ $resources | %{ if($_.ResourceMethods) { $path = $_.Path $_.ResourceMethods.Keys | where{$_ -notmatch 'OPTIONS'} | %{ $wildvalue = "Stage=$stage>Resource=$Path>Method=$_" Write-Host "$wildvalue##${Stage}: $_ $Path######auto.stage=$stage" } } } }19Views0likes1CommentAWS Lambda Alias
GX2WXT A single Lambda function might have several versions. The default Lambda datasource monitors and alerts on the aggregate performance of each Lambda function. Using the Alias functionality in AWS, this datasource returns CloudWatch metrics specifically for the versions to which you have assigned aliases, allowing you to customize alert thresholds or compare performance across different versions of the same function. This datasource does not automatically discover aliases and begin monitoring them (as this could very quickly translate into several Aliases being monitored and drive up your CloudWatch API bill). Instead, add only the Aliases you want monitored by adding the device property "lambda.aliases" either to individual Lambda functions or at the group level if you're using the same Alias across several lambda functions. To add more than one, simply list them separated with a single space - e.g: "Prod QA01 QA02". If an alias does not exist, no data will be returned. This datasource is otherwise a clone of the existing AWS_Lambda datasource with the default alert thresholds.19Views2likes1Comment
Tuning a collector to work on a t2.micro EC2 instance?
I know that it is not exactly recommended/reliable to use a 1GB/1CPU Core machine to monitor...but it seems that installing a "nano" sized collector on a t2.micro AWS instance and having it just monitor itself brings the AWS instance to a screeching halt. I am seeing that when the collector is running, top shows that CPU pegs to 100% almost nonstop. Memory is not hit quite as bad..but it does get up there to use 500mb+ But the CPU load average is 5+ cores and it makes the system unusable. Sometimes this causes the instance to throw status alerts & even crash. Question: Has anybody been able to tweak the wrapper.conf etc files to make the collector CPU load less demanding?Solved18Views1like1Comment
