Remember too that national contingents may be provided with intelligence support by their own national intelligence communities. In some cases this is marginal... in other cases, it is rather more extensive. It wouldn't necessarily all be shared with other contingents, or the UN force commander.

As UN PKOs see proportionately fewer developed countries contributing troops, the degree of national intelligence support to contingents declines. (It also depends on where the operation is, and hence the degree of SIGINT, HUMINT, and IMINT that is being collected in the first place.)
