Re: Ping Failing from collector to device and back?
This behavior seems like it may be related to, or overlap with, an issue I first observed in January 2020 (I think) and was never able to resolve. Randomly, subsets of our Juniper switches (and only switches, no other devices) would trip alerts indicating 100% ping loss. It would usually auto-resolve after 60-90 minutes and never left evidence behind--that I could find--why the condition started or cleared up. During the time the alerts were in effect,I had other non-collector sources of pings to the same switches that were not disrupted and I could ping back to the collectors involved from the switch command line. SSH, SNMP, other communication between collectors and switches showed no problem. Of note, none of the traffic between collectors and switches traversed a firewall. The real kicker to me was that I had never seen this behavior until I upgraded collectors to 29.003. If I rolled collectors back to 28.x, the issue did not occur. As soon as I pushed forward again to 29.x it started happening again. I opened a case with support and I spent a lot of tedious time trying to figure out where traffic was getting dropped to no avail; after several monthsI was not able to convince them to move from their “its something in your environment” stance. As much as I wanted an answer I simply could not afford to devote the time needed to sustain an investigation. Ultimately I applied system.category “NoPing” to switches and moved on.10Views2likes0CommentsRe: Ideas for tracking LM website docs changes?
👆 +10 I think this isn’t something that isn’t unique to LM, but it would be hugely helpful if they were able to figure out a way to add a calendar dimension to documentation content, a trail of milestones or a mechanism that let us essentially “flip back to a previous page”0Views0likes0CommentsRe: How to submit a Feature Request.
In general, I’d probably say that “Feedback” and “Feature Request” communication channels should get separated. An acceptableoption would be providing a choice at Feedback creation: “What is this feedback about? UI look & feel UI text, grammar, spelling error Product Feature Request” In both cases, as a customer I very much want to be able to track the progress of any feedback or feature request that I might make and as noted above the current mechanism does not provide this; in fact b/c I don’t even get an ack or receipt I am pretty sure that I’ve submitted the same feedback multiple times. So here’s hoping that the Feature Request pipeline (and the Feedback one too) is getting a makeover as part of this Community re-launch.4Views2likes0CommentsRe: What Additional Topics, Groups or Categories would you like to see?
I think I would find it valuable if there was a way to allow me to “associate” with other members based on products, services, technologies, vendors, etc that I have in common with them. The idea being that this would allow me another way to target my community questions, answers, posts and other input and to organize or prioritize the input that I see from others. Immediately thismakes me think of a VMware group, a Cisco group, an AWS group as examples. That would probably work but it also might become a huge unmanageable mess. Another idea would be to adda Profile section that would allow me to select pre-defined “tags” (there might/must be some way to automate their definition based on importing a value from the Modules or Integrations universes in the Portal UI?) For example, we use and monitor Juniper routers so maybe this would be a way for me to focus/constrain content & interactions with only other community members also using Juniper routers instead of all of those who use Cisco routers? Maybe LM would find thisinteresting enough to explore it further and see if where it (or any of the possible iterations) goes would lead to something that could be implemented here in the Community.1View1like0CommentsRe: Customizing HostStatus datasource to alert on "No Data" ???
After a little further review, the newest SNMP_Host_Uptime datasource is probably the best choice. It seems to be a universal hit in terms of both "AppliesTo" matching and returning valid data to polling/collection. snmpTCPUDP (TCP UDP stats) seems also universal in terms of "Applies To", but some of our devices return "No Data" 24/7. In addition, I have not been able to positively identify a historical situation where an snmpTCPUDP alert trigger on"No Data" would have produced the desired result, i.e. making us aware of the situation when other SNMP datasources were not doing so.20Views1like0CommentsCollector Group / Resource Group relationship
When you install a new collector on a Server, you can choose to "Monitor the device on which the Collector is installed" and select the device group to which you want the Collector to belong. This does make it super easy to begin monitoring the Collector and its host, but the next choice in the Collector install process is for Collector Group assignment. And right now there is no relationship between Collector Group and Device Resource Group. I would really like to be able to see my collectors in my resource tree in groups that match the names of the Collector Groups. Yes, I can manually accomplish this outcome. But I think it would be so much better if there was an option at collector install to make Group Name equivalency between Collector Group and Resource Group an automatic, dynamic occurrence. That might happen in the future by making a feature request but for right now, I'm stuck trying to think of how to accomplish this on my own. Seems like a property and a variable are needed, and then dynamic group membership based on that property/variable pair but this is where I've developed a mental block. Anybody tried this before?3Views1like1CommentRe: Customizing HostStatus datasource to alert on "No Data" ???
On 9/14/2022 at 11:01 AM, Stuart Weenig said: The HostStatus datsource should always have data, even if the device is not responding. We have a >300 threshold on the idleInterval datapoint. This is probably what I could not remember that I had realized in the past: there is never "No Data" for the HostStatus datasource. And so thanks for the suggestion of SNMP_Host_Uptime within the Host Status datasource group as a recommended candidate for triggering a "No Data" alert (The other on the short list is TCP UDP Stats). I have an older/deprecated SNMP Uptime DS still in use so this is a good opportunity to review the release notes and replace it. thanks.22Views2likes0CommentsCustomizing HostStatus datasource to alert on "No Data" ???
Can anyone share some feedback on customizing default global definition behavior for datasource HostStatus (HR6FND)? More specifically, I'm looking for some ideas about changing the behavior of either the heartbeat or idleInterval datapoints: by default neither triggers an alert if there is No Data. At some point in the past I thought about changing this so that an alert would be triggered, but then I seem to recall that there were some reasons where I thought this might produce unintended consequences and so I needed to consider more carefully and thoroughly whether this would be a good idea. Unfortunately, I never returned to that thought exercise and I also didn't keep good notes because I don't remember what those reasons were. Fast-forward to last week and we had a situation where a monitored resource suffered failure that we would have caught much sooner if we were alerting (to a chain with notification delivery) on "No Data" The resource did not stop responding to Ping, but nearly all of its snmp-based datasources/datapoints started returning No Data; without the alert and notification we did not realize that the resource had stopped providing service. So I'm thinking about this again now. Any/all ideas are welcome.Solved240Views2likes3CommentsAzure Service Health Event Source Alert help
Has anyone out there come up with effective strategies for adding filters to the Azure Service Health event source to suppress alerts that are not relevant to your environment? I'd like to figure out how to constrain alert generation to only those things that are relevant to us, whether that's inclusion, exclusion or match by service, location, keyword etc. I'm struggling to get started. Any ideas would be great and filter templates would be awesome. Using today's on-going Azure issues as an example, the default event source trips hundreds of alerts (thankfully we don't route them to notification delivery), all with identical message text. Since we haven't customized the event source, the resulting alerts also don't clear. Thanks.35Views1like0Comments
