[Ganglia-general] Gweb cluster page stopped working after adding 500 custom metrics per server
Hi All! We added ~500 custom metrics/server in one cluster and now this cluster page stopped working. All other clusters are working properly. It looks like some timeout value should be updated in Gweb, because the data retrieving time was increased. Do you know how to fix this? The mobile page is still showing all data from this cluster.

[Ganglia-general] Process state monitoring
Hi Everybody! I see that we can monitor any process and collect CPU and memory metrics for this process via Python module. Is it possible to monitor the state of the process (if running - state=Up, if stopped - state=Down)? I see that CPU and memory metrics are coming independently of the process state, so I can’t use them to calculate the process state. I think some “process heartbeat” monitor required. Any ideas?

Re: [Ganglia-general] Process state monitoring
Hi Vladimir, This is indirect solution. I’d prefer some python module which will return metric “100” in case of running process and “0” - if it doesn’t exist.

Re: [Ganglia-general] GMOND + SFLOWD functionality
Hi Peter, It’s very sad. It also contradicts the Gmond topology described in the O’Reily book “Monitoring with Ganglia” (p.22 Fig. 2-3). The main disadvantage of this is the fact that we have to build 2 parallel monitoring structures (gnome and show) with separate ports and flows, which are joined only in the central collection point. Is it possible to modify Gmond agent to join Gmond and Sfow data locally on every monitored computer? Thanks!

Re: [Ganglia-general] GMOND + SFLOWD functionality
OK. Then what does the “deaf” Gmond make with metrics to provide them to “mute” Gmond? I guess - it sends them. I our case “deaf” Gmond gets metrics from local HSFLOWD and doesn’t send them. Why it doesn’t send them to “mute” Gmond? What’s the difference between it’s own metrics and HSFLOWD metrics? Did you see the content of HSWLOWD.auto ? It says that Collector IP should be “localhost”. But it can’t be localhost because collected metrics will be saved but not transmitted. Thanks!

Re: [Ganglia-general] HTTPD metrics not sent
Yes, and I see in debug mode that GMOND accepts and saves HTTP metrics. These metrics can be retrieved over direct TCP connection from Collector, but they are not sent to another GMOND agent via UDP.

[Ganglia-general] Sflow Apache metrics
Hi All! I installed mod_sflow on Apache and try to collect HTTP metrics by Gmond. The problem is that I don’t see any HTTP metrics coming from Hsflow to Gmond, nor HTTP counters via Apache http://hostname/sflow http://hostname/sflow page. There is a list of counters, but they all have 0. Like this: unter method_option_count 0 counter method_get_count 0 counter method_head_count 0 counter method_post_count 0 counter method_put_count 0 counter method_delete_count 0 counter method_trace_count 0 counter method_connect_count 0 counter method_other_count 0 counter status_1XX_count 0 counter status_2XX_count 0 counter status_3XX_count 0 counter status_4XX_count 0 counter status_5XX_count 0 counter status_other_count 0 string hostname xx gauge sampling_n 0 At the same time http://hostname/server-status?auto http://hostname/server-status?auto is working properly: Total Accesses: 15 Total kBytes: 5 Uptime: 149 ReqPerSec: .100671 BytesPerSec: 34.3624 BytesPerReq: 341.333 BusyWorkers: 1 IdleWorkers: 7 Scoreboard: Is there a way to troubleshoot this?

Re: [Ganglia-general] Gmetad-to-Gmetad connection
Hi Vladimir, I changed to “scalable on”. I didn’t help. What I see is only the common remote grid view: CPUs Total: 120 Hosts up: 16 Hosts down:2 == Current Load Avg (15, 5, 1m): 3%, 3%, 3% Avg Utilization (last hour): 4% Localtime: 2015-03-25 10:27 === I can’t see any clusters and hosts inside this grid. By netstat I can see that the second Gmetad instance on machine2 periodically connects to the machine1:8651. I don’t see any connections to machine1:8652. The second Gmetad instance has the same ports, but it’s on another machine. Did you mean that it can affect the polling process? Any ideas? Thanks!

[Ganglia-general] Ganglia web question
Hi Everybody! I’m new in Ganglia. In my current configuration I see that Gweb and Gmetad services are running on the same machine and all data is collected on this machine in RRDS storage. Is it possible to keep all data only on Collector machine with Gmetad and RRDS and access to it from Gweb remotely? If yes - what should I change in conf.php in Gweb configuration and what should be done on Collector machine? Thanks!
