Rosler's influence at the DW Stadium gained his side four wins in five matches.
One of those successes was a vital 2-1 victory at promotion rivals Brighton & Hove Albion - inserting belief and solidity in his team.
Dave Bassett chairs the Sky Bet Manager of the Month judging panel and he said: "Uwe has moved his side firmly into play-off contention as we enter the business end of the season. He's made a fantastic impact at The DW Stadium, coupling impressive league form with progress in the FA Cup."
Burnley frontman Vokes landed the Player of the Month award after stealing the spotlight at Turf Moor with five goals.
He produced two lovely finishes against Millwall as he continued his dynamic partnership with Danny Ings.
Vokes told Sky Sports News Radio: "We've had some very tough games in this last month and some big games at the top of the table so we've managed to come through those with some big results, and it's been a big team performance from the lads. It's been a good season so far and there's hopefully a few more (goals) to come but it's been a massive team effort and I think the lads have been brilliant this year."
In Sky Bet League One, Nigel's Clough efforts at Sheffield United have been rewarded as a frantically busy February delivered four wins from five games and FA Cup progress as the Blades embraced their manager's principles of hard work and solidarity.
Clough's team kept four clean sheets and moved up to mid-table.
Bassett said: "Having started the month in the relegation zone, Sheffield United have surged up the table. Nigel's men played seven matches last month, so to maintain such consistency in the League and the FA Cup is an impressive feat."
The player award went to Wolverhampton Wanderers' Michael Jacobs, with the 22-year-old netting four times in three games.
He scored twice against Notts County and twice again in the 3-0 win at Brentford, arriving at pace for the first and striking a composed curler for the second.
Jacobs told Sky Sports News Radio: "It's a great honour. I've been at Wolves a couple of months now and it's always nice to pick up an award and obviously shows how good the form has been this past month or so. It's a nice honour and I'm very thankful. I've contributed a few (goals) but it's been down to good attacking play from my team-mates, and I'm thankful to them. It's nice to get a few goals and hopefully I can go on a bit of a run now."
Meanwhile, Bury boss David Flitcroft has taken the Sky Bet League Two prize after seeing his shrewd January acquisitions bring about a dramatic transformation in performances and results.
Bassett said: "David has had a major influence following his appointment. Bury's unbeaten month secured an extremely valuable 11 points - steering them away from the relegation zone."
Rochdale's Scott Hogan was picked out as the star performer in the fourth tier, with the striker finding the target four times, including a 16-minute hat-trick in a 3-0 win at AFC Wimbledon.
His other goal came via a curling finish after a forceful run and shot against Morecambe.
Hogan told Sky Sports News Radio: "It's a really good achievement for myself and the team, and I'm over the moon with the award. I want to thank everyone, the fans, the players, the staff and everyone involved. It's been a really good month for myself but more importantly it's been a really good month for the team. We're kicking on now and hopefully we can carry it through until the end of the season and see where it takes us."
