Metz went into the match looking for a first win of the season, but it was the league leaders who started on a positive note as Eiji Kawashima denied Julian Draxler and Cavani with a double save in the 11th minute.
The home side had a chance of their own but were denied by a brilliant Marquinhos tackle, before Thomas Meunier went close with another effort at the other end, but was only able to find the side netting.
But the game approached the half hour mark, Cavani came through for PSG, as he gave them the lead, after he was put through by an excellent through ball by Neymar, before rounding the goalkeeper to slot into an empty net from close range.
Metz responded brillianyt and were level moments later, as Rivieri headed in an equalizer after a brilliant work to evade a sea of PSG players by Mathieu Dossevi.

After the break, a mistake by PSG goalkeeper presented Metz a chance to take an unlikely lead, but Rivieri missed with the goal at his mercy.
Five minutes later, the hosts were reduced to ten men, as Assou-Ekotto was given his marching orders for a reckless tackle, though replays show that the former Tottenham man got the ball before taking the man along with him.
Nevertheless, PSG took the lead thereafter, and it was the man of the moment, Mbappe, who latched on to a loose ball to smash home a fierce effort for a perfect start to his PSG career, restoring his club’s lead.
Mbappe almost grabbed a second goal minutes later , but his effort was cleared off the line, before Cavani rattled the woodwork with a ferocious shot.
However, you always knew it was coming, a Neymar goal, as the world most expensive player made it 3-1 on the night for PSG.
The Brazilian created space for himself, after receiving the ball, before letting fly from range an effort that went past Kawashima in goal to give PSG a breathing space for the first time in the game.
With 15 minutes left to play, Cavani scored his seventh of the campaign, and PSG’s fourth of the night, as he taps in from close range to hand PSG a 4-1 lead before he was substituted alongside Thiago Motta for Lucas Moura and Lo Celso.
Moura would complete the rout three minutes from time, as PSG sealed a fifth successive win to remain unbeaten after five matches.
