Questions[hyperic](server)

We are testing out Hyperic 4.5.1 in a quite small environment for now. Currently there are just 1-5 agents and there probably won't be any more than 10-15.

When I run ps ax there are 20(!) postgres processes running. For a small setup like this, that can't be necessary, can it? I'm a software developer and don't have much experience with setting up servers and such though, so don't really know.

Either way, what settings are appropriate for a small Hyperic setup like this?

Current, default and untouched configuration file, hqdb/data/postgresql.conf:

# -----------------------------
# PostgreSQL configuration file
# -----------------------------
#
# This file consists of lines of the form:
#
#   name = value
#
# (The '=' is optional.)  White space may be used.  Comments are introduced
# with '#' anywhere on a line.  The complete list of option names and
# allowed values can be found in the PostgreSQL documentation.  The
# commented-out settings shown in this file represent the default values.
#
# Please note that re-commenting a setting is NOT sufficient to revert it
# to the default value, unless you restart the server.
#
# Any option can also be given as a command line switch to the server,
# e.g., 'postgres -c log_connections=on'.  Some options can be changed at
# run-time with the 'SET' SQL command.
#
# This file is read on server startup and when the server receives a
# SIGHUP.  If you edit the file on a running system, you have to SIGHUP the
# server for the changes to take effect, or use "pg_ctl reload". Some
# settings, which are marked below, require a server shutdown and restart
# to take effect.
#
# Memory units:  kB = kilobytes MB = megabytes GB = gigabytes
# Time units:    ms = milliseconds s = seconds min = minutes h = hours d = days

I am monitoring a number of enterprise resources with Hyperic and have a hard requirement to monitor their log files both for content and for size, as they have a habit of growing out of control.

Monitoring the content is easy, but I'm not sure how to monitor the file size. Is this something that can be done out of the box or would it need some groovy scripting to accomplish?

I've been running Hyperic for a few months now and for the most part I'm pretty happy with it. I have recently noticed however that the agent process seems to hog 100% of the cpu every 15 mins for about 30 secs. The servers are windows 2003, the hyperic agent is version 4.0.3. Some googling hasn't turned up much of any use. I'd appreciate any pointers as to how I might further investigate this, or suggestions for a cure if anyone else has seen the same themselves.

Is there an easy way to get metrics on all processes that start with the letters XYZ? I have about 80 processes that I have to monitor individually that all start with the prefix XYZ.

I have created a query using the sigar shell: ps State.Name.sw=XYZ, which will give me a list of the processes that I want. What I need to do is define this list of processes through said query and collect and track statistics from the Process service: http://support.hyperic.com/display/hypcomm/Process+service

What I need is 3 or 4 key statistics for each of the XYZ processes defined by my query to show up as graphs in the web front end.

Note: Hyperic HQ server is installed on a windows machine and I'm monitoring a Linux box via an agent.

Thanks,

Chris

Edit: Here is my try at a plugin that may give me what I want, but it's not being inventoried/detected by the Hyperic web UI. Simply pointing me to one of Hyperic's tutorials won't do. Thanks.

I've been trying to find a good solution (that can run on Windows) for monitoring/trending/alarming a distributed system comprised of primarly Java technology (Tomcat, ActiveMQ, JBossCache, etc.), but also some .Net and MySQL/SQLServer. Hyperic HQ (open source version) seems like a reasonable solution, although it doesn't support the latest version of Active MQ (5.2) or MySQL (5.1). I was wondering what sort of experiences others have had. Any advice, war stories, or alternative solutions would be greatly appreciated.

As an aside, the company I work for has adopted for general perpose monitoring ELM from TNT Software. It has many nice features, especially when it comes to centralized logging and process monitoring. However, it lacks specific detailed metrics and monitoring that Hyperic HQ can provide for many of the services that we use.
