OT What is this in the electric pole?

Taking a walk and sat down by a wood electric pole, not carrying any
electricity, just put on one side of the street to balance the tension
from the other direction on the pole on the other side of the street.

About a foot above the ground is a 3" section with 3 things in it, all
pointing down, about 30^ from vertical. The top one was a wooden plug
about 3/4" in diameter. The next one down was a wooden plug about an
inch in diameter. And the bottom one was a metal thing, black, looks
like a plug, almost an inch in diam. with a hole for a pretty large torx
wrench in the top.

What do you think these things are?

Possibly, they can load some wood preservative into the core of the pole? I found the plug...but it didn't detail its use.

"Treated Wood Plugs
There are 22 sizes, lengths and quantities of treated wood plugs available from our large inventory. Poles, Inc.'s famous camouflage colored 5-gallon pails, filled with plugs, can be found in the trucks of contractors all over North America. The pails offer an economical and easy to use option for shipping plugs. Treated wood plugs are treated with either Copper Naphthenate, CCA, or ACQ. Tight fitting plugs should be placed into all of the inspection and treatment holes that are placed into the pole during an inspection.. Treated wood plugs are also used to fill abandoned bolt-holes in the above ground portion of the pole. Utility companies often move cross arms or reconfigured wood pole lines during there long service life. Leaving these holes open can allow for above ground decay or insect attack to develop."

May be it is to inspect for core rot?
