# Tail for the integrale of a diffusion process

hello, I would like to compute the following tail

$\mathbb{P}\left( \left[ \int_{0}^{T} f(X_t)dt \right] >x\right)$ if $\mathbb{P}[f(X_t)>x] = x^{-\alpha} \log(x)$

X is a Diffusion process meaning that $dX_t = b(X_t) dW_t + c(X_t)dt$ where $W$ is a brownian motion, $b$ et $c$ are given functions\ Thanks in advance
