monitoring open http sessions on a jboss server
by Attila Heidrich 18 Jan '18

18 Jan '18

Hi, is there a way to monitor the open sessions of a jboss server? I see I have some metrics for the http connector, and the requests per second value is really useful, but we need some more detailed statistics. It would be the best to have some browser to select the parameters... ;) for webapp dveelopers it would be such a great benefit! Afaik, there're some internal values in the jboss server, should I extend the JBoss plugin to get a value, which isn't got now? Attila

RHQ plugins by iAd
by Elias Ross 03 Nov '14

03 Nov '14

I have just released a number of plugins, mostly for monitoring OSS software here: https://github.com/genman/rhq-plugins Some of them are a bit rough around the edges, but most have been in use for many years at my company. The most significant one, I think, is the SNMP plugin, which can generate a working plugin descriptor for any device that has a MIB. Included are plugin descriptors for Citrix Netscaler, Fusion-io, and NetApp filer generated by the plugin. Obviously cleaning up the descriptor may be required in some cases. For the full list: https://github.com/genman/rhq-plugins/blob/master/README.md

Sizing guidelines for future RHQ inventories
by Lukas Krejci 27 Oct '14

27 Oct '14

Hi all, we are starting to re-think RHQ to bring it forward to the cloud-ready, IoT and other brave new worlds and would like to hear your feedback on what an RHQ inventory might "look like" in the future. I am basing the below on the forum article https://developer.jboss.org/en/rhq/blog/2014/09/25/thoughts-on-inventory-fo… (including comments and links) which describes in high level our current thinking about the architecture of the new inventory. I just pulled some random numbers almost out of thin air (the sizing is based on the anecdotal evidence I gathered from the community about the sizes of the larger inventories people are managing). I'd like gather feedback on both the numbers and the structure of the inventory. To mimick the basic, still important, tree structure of the classic RHQ inventory: * there is 1000 agents (machines) * There are 50 resource types * Hierarchy is 7 elements deep * There are 10 types of top level resources * 5 of the top level resources have children (think servers per machine) * only 2 resources have full 7 element deep hierarchy * There are 10 resource groups * All resources are part of at least 1 group (either explicitly or implicitly) * Every resource has 5-10 metric schedules, 2 operations * Plugin config of each resource has 2-20 properties * Resource config of each resource has 2-20 properties To mimick the new requirements: * Each resource is part of 1 application (either explicitly or implicitly) (did I hear these are the same as mixed groups? ;) ) * 1% of the resources is part of 10 applications (shared infra like db server) * Each resource has 5-10 versions (to mimick changes in config/schedules) * There are 10000 "miniagents" (some on machines managed by the "real" agents, some outside of them) * Each miniagent defines 1-10 resource types * 5 of these resource types are equivalent to the resource types from full- blown agents * mini-agent defines 1-20 resources which have metrics and configs with the same sizing as on the real agent. No operations though. WDYT? I am going to use these guidelines as a basis for a benchmark that should help us choose the right storage solution for the data. The benchmark will be mostly focused on query performance because the inflow of the data won't be that huge with rhq-inventory (meaning the rate of change of the inventory itself is not going to be big). The rhq-inventory endpoint will have a high throughput component that will establish identity of the input data but that is mostly not going to end up being persisted. It is most probably going to be merely routed somewhere else (metrics, audit, alerts, ...). Thanks, Lukas

Apache Plugin
by mark christian 23 Oct '14

23 Oct '14

Hi, We’re newcomers to RHQ and are using it as a POC at present for JBoss admin, we would like to eventually use it for Apache admin too but have an issue. The plugin code checks for a valid version using “Apache/” to catch version 2.2.24 from “Apache/2.2.24” for example but our Apache installs were compiled (for unknown reasons) with our company name rather than Apache so RHQ won’t discover automatically or manually any of our Apache installations as it believes it's not a valid version. Is there an RHQ wishlist that I can add this request to please? *Regards* *Mark*

RHQ/Sharepoint interoperability
by barry.barnett＠wellsfargo.com 22 Oct '14

22 Oct '14

I am wondering if I can take information from our RHQ implementation and have it show up on our Sharepoint site. We are running RHQ v4.11 server. Is it possible to connect RHQ into Sharepoint, or do I need to concentrate on the JBoss server that RHQ is running on, and use the JBoss Portal to connect in? Can anyone assist in answering my question?

Planned deprecation of the rhqctl upgrade --start option
by Jay Shaughnessy 08 Oct '14

08 Oct '14

This is an FYI that we're planning to deprecate the rhqctl upgrade --start option in RHQ 4.13. I'm wondering is there is any push back from current users? Upgrade is a multi-step procedure for anything other than a single server/storage node, co-located install. Moreover, 4.13 will introduce a new step for updating the storage cluster schema. The convenience of an automatic start option is outweighed by problems caused trying to start a component prior to the entire RHQ Installation being completely upgraded. The deprecated option will still exist, only for backward compatibility of command structure, but will likely only generate a warning; it won't actually start any component.

Enable Web Services for RHQ v4.11
by barry.barnett＠wellsfargo.com 02 Oct '14

How do you enable Web Services for RHQ v4.11? I want to be able to have a Sharepoint site interface with the RHQ Web Service to show the General RHQ Health page on our site...
