Environment alarms @ ICL 

By: TeX
Time: 2008117 1007Z
Music: NONE

Got these alarms:
0814Z	Sensor - Temperature
	Current value - 90.01F
	Alarm thresholds - ( 50, 90 )
	Event - High trip alarm
	Device - "goose3 ICL: Top of Rack13" ( WxGoos : 01A6EDBD0F0000B6 )
0827Z	Sensor - Air Flow
	Current value - 19.14
	Alarm thresholds - ( 20, 90 )
	Event - Low trip alarm
	Device - "goose1- ICL: Top of Rack1" ( WxGoos : 01B849BD0F0000D2 )

0828Z	Air flow cleared, but flapped until finally clearing at 0846Z

	The weather goose web interfaces show the temperatures have been
	going up the last few days, presumably due to the warmer weather.
	The sound level has also gone down, presumably due to less need to
	heat the room?

	It is unclear to me what temperature the temperature alarm is giving,
	it doesn't seem to indicate which sensor did the alarm and looking
	at them makes it not clear.

	In addition, on the web interface, for a given temperature sense it
	will give a temperature, but the temperature shown on the graph is
	different by at least 2 degrees, often more.

	So double checking temperatures on the HP sysman interfaces:
	gull (32-41C)
	sps-cvmaster (40-50C)
	sps-2ndbuild - can't get on for some reason
	sps-sattx2 - (40-53C)
	sps-expcont - (37-45C)
	All of these are well within the limits shown on the interface.

	Used the mrtg interface to look at the hubs, looked at quite a
	few of them, ranging from 44-52 in temperature, presumably C.


	The airflow ones are continuing to flap now.

2026Z Temp alarm finally clears:
	Sensor - Temperature
	Current value - 88.97F
	Alarm thresholds - ( 50, 90 )
	Event - High trip clear
	Device - "goose3 ICL: Top of Rack13" ( WxGoos : 01A6EDBD0F0000B6 )

2204Z	Looking at the graphs, looks like things slightly cooler now.
	The airflow is still flapping quite a bit.

2008118 0751Z After watching the latest Lost, I ran in UT JT who said he
	got an ICL temperature alarm for room 205 of 85 degrees. Neither of us
	know which room 205 is. I haven't gotten any alerts from our
	environmental monitors. Values on the weathergoose graphs are
	certainly lower than yesterday, perhaps rm 205 is not the computer room?.
	The UT said he would go out tomorrow unless I find some issue that
	needs to be fixed now, which I don't.
